Conversations involving multiple participants, allowing collaboration and information sharing in Teams
I came across this issue today for the first time.
I'm also running Teams Version 1.5.00.5967 (64-Bit).
Yesterday was the first time in ages when I didn't reboot my PC after a days work.
Might be a reason why I didn't encounter that issue up until now.
It's astonishing, that this thing is going on for almost a year now and it's still not resolved.
Even more so when you consider that Teams is one of the fastest evolving apps Microsoft currently has.
