We've noticed that the Entra ID connector, when adding a user to a group, is suddenly removing the user from the Teams M365 group less than a minute later.
I verified this behavior to be true by using the graph explorer to add the same user to the same M365 group - user was never removed from the group. I also can add the user manually to the group without them being removed. Something is suddenly wrong with this connector, as everything else with the flow is functioning just fine. To further clarify, NO error shows up on the flow - it states the user was added to the group and User/Group audit logs in Entra reflect this, then about ~30sec later you can see the account be removed from the group with the acting author as, "SkypeSpaces/1.0a$*+"
