I want links to external URLs on my blog to open in a new tab. I follow the instructions that Squarespace offers but it does not work. See screenshots below.

I can toggle the option on but as soon as I click outside the block editor the toggle goes back to being off. 

Any idea when this issue will be fixed? It's pretty vital that we are able to have links open in a new tab.

Thanks, 

April

I am using Squarespace 7.0 template "Ahmir Miller" and I would like a fixed header. Is there some custom CSS I can use to make the top navigation static?

That worked beautifully, thank you!

I want to remove the date from every blog post. Like this one, for example: https://aprilrose.dance/blog/boosting-your-creativity

How can I remove the published dates from blog posts?
