Conversations involving multiple participants, allowing collaboration and information sharing in Teams
I have the same issue - and I have had a similar issue in other MS apps like outlook and word where ctrl+arrow stops working when I have accidentally turned on the 'screen reader' or narrator or whatever it is called using a keyboard shortcut. But i cannot find whether narrator exists for teams or how to turn it on or off.
In any event, the "answer" at the top of this thread is terrible - unclear, too complex for a normal user, and if this is the result of a feature providing unexpected unwanted outcomes rather than a bug, this needs to be resolved as clearly it is causing more problems than solving!
I guess if you have this problem keep reporting and commenting so it stays as high as possible on MS's monitored questions
