Phone sync-main app won't shut down

If I have to stop syncing playlists to my phone (which happens routinely if I have too many tracks or playlists and it wigs out on me), I can stop the phone sync, but the main Lexicon app on laptop won’t stop. It’s like it thinks it’s still syncing to the phone. Quitting Lexicon won’t work. I have to force quit every time

Thanks, I will investigate. Normally it should stop when the app stops since there are no more signals reaching Lexicon
