Editing pages issue - SameSite Cookie Attribute

Hi there, 

I am a newbie in squarespace, and I'm finding hard to edit objects when editing pages. 

I've been searching and it seems it has to do with some cross-site cookies. I found a solution in this post , but after disabling all 3 options and restarting the computer, the issue is still there.  

I am using Windows and the issue happens in every browser, however, my partner's MacBook doesn't seem to be affected by this.

I believe this is an issue that squarespace should fix.

It Will be great if anyone has any additional solution. 

Thanks.
