Btw Jeffrey Allen , have you ever check in AppData\Roaming\Microsoft\Teams there is a file named setting.json?
When I am not in Public Preview, the first line shows that I am in ring "general". If I switch to Public Preview, I am in "ring3_6". May be you can check yours to see which ring you are in when in Public Preview. The setting.jason file can be opened with notepad.
Till today I still don't understand why Public Preview doesn't get some preview features activated when they are released. Yesterday I just got Dynamic View and Presenter Mode activated along with may be the whole users in my organisation, while those features supposed to be available for Public Preview months ago ahead form general users. My guess that these features are tenant level features that should be activated for the whole users at once to be working. If so, then what's the point that they released them for Public Preview. I really hope that MartinRinas can give clear explanation.
Thank you
