I am a owner of a team.
But when i go into the teams settings as owner (both client and web on Windows computer).
I can not see who is a member of the teams.
I see myself as a owner. But under Members it does not show anything.
But still i am talking to my members in the teams conversation.
Its like everything is grayed out/locked under member tab in the team settings.
If i open the team settings on an Android Phone, i can see all members without any problems.
Do you have the same problem if you sign in from another computer or use the web client https://teams.microsoft.com ?
