If you are on Mac with OS version Catalina or later, and your teammates are not seeing Activity Presence for you, please verify that you have the Screen Recording permissions on.
Go to Apple > System Preferences
Click on Security & Privacy
Click on the Privacy tab in the modal popup
Scroll the list on the left to Screen Recording and click
Confirm Loop Team is checked
Restart your Loop Team app and try again
Keep in mind:
The Screen Recording Mac OS permission is also required if you wish to screen share from Loop Team
The Mac OS permission is awkwardly named as Loop Team does not do any "screen recording"
