Please, help me with this issue.
I use an iMac.
Thank you for your post, and welcome to the TeamViewer community!
The "m" at the beginning of the meeting ID is meant to be there, and is a part of the meeting ID itself.
If you could please let us know the specific error you encountered when attempting to join the meeting, we can help clarify and prevent any issues for your meetings going forward.
Thanks in advance!
