I can't click on the shortcut tool for editing text

Hi,

Since a few days back I'm not able to use the shortcut tool for editing text on Squarespace 7.0. I did notice they recently changed the interface a bit, and since then I'm not able to click it.

For example:
If I want to make a link in a text, I mark the word I want to make a link for and a shortcut menu opens up. However, when I click on the "make a link" icon, the menu shuts down. Until now I've used "cmd + K" to get around this issue, but now that doesn't work either.  

Anyone with the same issue? I've reached out to Squarespace but they said they can't help with this.
