I have a project where clicking ‘use dynamic value’ for a vertical stack visibility is causing the page to immediately freeze and then crash, every time
I had a similar issue yesterday when clicking to set a dynamic value for any element would cause the page to be unresponsive and hang. It turned out I had an incompletely configured query on that page. I deleted the query and everything worked again. If that’s the case for you, either make sure your query is correctly configured or simply delete it if not needed.
We are currently working on a fix for this. Sorry for the trouble!
