Just got a new update first thing this morning. Brought my tab up to Android 10 and UI 2.1. Not sure of what the other changes are yet as I had to leave for work after updating. Guess I'll see when I get home.
Not sure about the edge panel. I never thought to look but I'll check when I get home from work. The update seems to have made my entire tablet buggy. It's slower and seems to freeze up while scrolling and using apps. I'm definitely not impressed.
