Arc Sync Issue Samsung S10 Plus

Hi @Pete_Lee
I’m sorry you’re having such troubles with your phone and ARC.

The whole thing reminds me badly of months of uninstalling, reinstalling, deleting caches, sending adb logs over and over, never-ending hassle with my Note 10+ and Roon remote (ARC didn’t exist then).
Of course I cannot know if your issue is related to my case regarding possible problems with Samsung’s One UI and Roon.
But I would like to point you to my thread and the solution I finally found by pure chance. It could possibly save you months of trouble.
