Galaxy Watch 4 after updating to Watch UI 6:

• If I use any sport or mode, such as theater mode, the sound settings do not revert.
• During water lock, I cannot use the watch. The screen does not recognize any input.
• Workouts remained in the background and did not show a small icon at the bottom. I managed to fix this with some instructions.
• The screen turns gray when pulling down the watch screen from the top.

Could these issues be fixed, please?
