The in-meeting chat option is disabled all of a sudden. It was working fine till a couple of hours back. It does not work when my team joins a MS Teams meeting from a calendar invite.
We get a message "only team members can chat. Ask the team owner to make you a member." The option is however available when a meeting is started with a "Meet Now".
The configuration enabling chat has been done correctly in Teams Admin (see screenshot attached)
I have tried logging out and logging back in , restarting etc. Nothing seems to be working.
Appreciate help and guidance at the earliest as we have a series of webinars planned in a couple of days.
