Bulletin app won't open after moving to another channel
Here is the case:
I tried out the Bulletin app now for a week in teams to keep my team up to date.
So I opened the Bulletin app for the first time and see some standardized example articles. So I went to the the "manage bulletin" section and published some articles that I made myself. I also removed the example articles.
When I switch back to the bulletin app to see the result it won't open anymore. Only if I shut down Teams completely and then open it, it will open the bulletin app.
It seems that every time I open the app for the first time it will open, but every time I move to another Channel, App or else in Teams the app won't open anymore.
