Looks like remote support is not possible on Mac OS Big Sur. I can connect, but cannot see any windows, desktop icons, and browse the file system while connected remotely. Resetting privacy permissions and regranting did not resolve.
Looks like here Solved: Re: File Manager not connecting, Remote works fine... - LogMeIn Community that this is a known issue but has a workaround or solution been made yet?
@ekamper Can you try this user-found workaround on the problem Mac to see if it helps with screen sharing? https://community.logmein.com/t5/LogMeIn-Pro-Discussions/Logmein-Pro-Client-compatibility-with-Apple...
