Today I logged into Office.com admin portal, then went to teams. I went into a team and it randomly changed the members/owners. It did this each time I went in.
If I changed the membership status of a member from member to owner, it'd actually allocate someone else. It'd also make me leave the team.
Screenshot from Teams activity window below... It says "Rafe Aldridge" made lots of changes but I didn't! I just went into the edit screen for the team. I never left the team nor did I make Terran Churcher, Sam New, Phil Mayger or Jessica Penning owners at any point.
In the end I left the portal and used Phil Mayger's laptop to get me back in the team and make me the owner.
