We have used GTM for over almost 20 years. When the new client came out a few months ago we began having issues. This post is about Microphone and Speaker settings that don't stay selected between sessions.
We would be starting a call and 1/2 of the participants couldn't hear or couldn't speak. In the new version, the settings aren't up front and center so you have to hit the cog to find out if everything had changed.
Tech support switched us back to the "Classic" old client as a fix.
Embarrassing calls occurred with clients where we were saying "turn on your mic", or "turn on your speakers" just to find out that GTM had changed the setting between calls. Very unprofessional.
Of our 17 offices, half have changed to Zoom as a result. Hoping changing back to Classic will help.
