Can not switch status from busy

My status is permanently set to busy. Can not switch to “away” or “available”

When that happens, try switching your status to “Available” using the Blizzard Desktop App. This should set it properly in-game.

I have the same Issue. Busy status, when I change it to available it goes back to busy as soon as the box closes.

Switching status to available using the desktop app doesn’t fix it

I have had this same issue with not being able to change my status with both the blizzard app or in game.
