I have a List/Library control that I set a root folder. It works fine using a Browser. Currently using Google Chrome, verified Edge as well. However in Teams the root does not set.
Here is the view in Chrome:
Also, I am having an issue with a form set since update. Most are working. There is one in particular that is not. I have tried exporting and importing, saving... When a link is selected to go to the form it directs to the default form.
I found that I was still routing to individual pages rather than using FormID=...&item. It is fixed now. Sorry I was in a bit of a panic after upgrading.
