Just installed the latest update. It looks well and works fine. I noticed one little thing : some extensions do not work anymore. Todo.txt and the drop down terminal.
Update
That's normal for basically any GNOME Stack upgrade, there are always going to be extensions that break. You'll need to reach out to those developers and ask for support for GNOME 3.36.
Thanks for your answer. Now it's clear to me. Thank you very much.
