The code is in Store Settings > Advanced > Page Header Code Injection for the store page. Please see per-page code injection.
Remove the following.
<style> .ProductItem-details .sqs-add-to-cart-button-wrapper { display : none; } </style> Let us know how it goes.

I can confirm that no matter how the accordion block is duplicated the bottom and top border are always turned on.
I would consider this a bug. It is not WSIWYG!
For some CSS please see the following.

I don't have a solution but I can describe why things are not working as one might hope.
You've included a full HTML page inside another HTML page and HTML doesn't work that way. It's a syntax error.
A developer would have to see if they can pull out the critical bits and include/modify them to work in a Squarespace site context. Another option might be to host the full page on another hosting service and pull the page in with an iframe in a code block. Each method has its challenges. I would not classify this task as easy.

This appears to be a bug on Squarespace's end.  I checked several v7.0 sites and they are all doing this.
I suggest reporting the issue to SS. Please Contact Customer Support.

I'm not sure if your question is if you have to do something to get the mentioned pages indexed. Or, if you don't want some pages indexed for some reason.
In theory there is a chance that your pages will be indexed naturally. No one can guarantee when or if it will happen. Being indexed and searchable on Google depends on many factors.
You can increase your chances by getting an account on Google Search Console and submitting your sitemap.xml file to it. But again there are many factors that go into success. GSC also gives you reports about Google's indexing activity that can be useful.
If you don't want some pages indexed there is a technique to do this. It has been mentioned many times in this forum.

Edit your Additional Info for the product.
Place a line block above the first text block ( the one with the unwanted color ).
Above the line block add a new text block. Enter the text from scratch. Don't copy and paste the current bad text. Also do not set a custom color for the text.
Apply the Additional Info and Save the product.
Check the new text. Does it look OK? If so, go back in and delete the line block and the bad text block.

You can't stop people from sharing login information and tracking such behaviour is not a thing.
Plugins aren't going to help as they could easily be disabled client side.

I do! The issue is a non-printing character has gotten into the mix and causes the ruleset to fail. If you look at the ruleset you will notice two characters between the selector and the right curly bracket ( { ).
Select the two characters and type the space character. Or, you can use the following.
@media screen and ( min-width : 768px ) and ( max-width : 799px ) { .header .header-announcement-bar-wrapper { padding : 3vw; } } Also note I change the 798 to 799.

Just a general note for folks.
Although things like DNS changes and SSL certificates usually take much less than the 72 hour recommended waiting period. There are those occasional circumstances when it does take the recommended wait period.

v7.0 sites use a single editor for both desktop and mobile.
Your issue is probably due to unintentional nesting of blocks.

 
Notice how the two coming soons are not on a row on their own. They are laid out in a column under the videos.
The way columns wrap when viewed on mobile is the ones on the right collapse under columns that precede them.
So on desktop you have...
column 1    column 2
...and on mobile you get...
column 1
column 2
So you can see with thee layout you have you get an interleaving you probably don't want.
To reduce unwanted nesting of blocks I use the technique of using line blocks that span the whole width. Something like the following.
Line block
block    block
Line block
block    block
Line block
block    block
Line block
Then when everything is laid out the way I want, I remove the line blocks.

Yes you can add another member who is a Circle Member and have them change the setting.
I'd be happy to do this for you. Direct message me and we can set it up.
Whichever Circle Member you invite will need a Contributor invitation with administrator permission.

I can't speak to the MailerLite JavaScript itself working on a SS site.
As to running JavaScript on a SS site, that requires the business plan or above.

The gallery section is still set to height medium. Set it to large and Save.
The section with the code is set to large. It should be medium.
If those section heights aren't set correctly. Then the CSS code won't work.
I also updated my code. There was a missing ruleset.

This is the issue. Gallery sections don't have themes and your current CSS is targeting the theme classes to add your effect.
For the homepage you may want to use a selector like the following.
.homepage .header-mobile-logo a Let us know how it goes.

Add the following to Website > Website Tools > Custom CSS.
/* workaround for header social icon spacing issue */ .header-actions--right .header-actions-action--social { font-size : 0px; } I suspect you have at some point modified the sites font styles perhaps increasing the size of some of the site elements?
This appears to be causing an issue with the spacing around the header social icons. I would consider this a Squarespace bug.

No. You can hide it visually in the browser but that hiding has no effect on what SS expects to receive when the form is submitted. Hence you have to supply a value for the Last Name field behind the scenes.

Perhaps your issue is related to the following.
 
 

For folks that may not readily see the solution. Set the Stock to zero for A4/None and 60 x 90 in/Metal in the case of this particular scenario.
SS is a bit funky in the way it handles variants. There is some fallout from this set up. The from price always shows zero. To overcome this you can set the price for the non-existent variants to the lowest of all the prices. You just have to remember to never set the Stock to non-zero values. You also get Sold Out messages if you select one of the non-existent variants.
It may be possible to overcome these "features" of how SS does things with some custom code. You'd have to search the forum or ask a question for a particular need.

I updated my code. Please try the revised version.

Add the following to Website > Pages > Website Tools > Custom CSS.

This isn't an issue with the scrolling text. The issue is header actions is overflowing due to the following custom CSS.
