All my keybinds reset themselves

when I logged in today, all my keybinds were reset and I was getting beginner tutorials.

The only thing I did today was install Overwatch 2, would that have caused this?

Howdy Arcadium,

Installing OW2 should not have caused this. Based on what you described, the D3 files may have been reset or changed for some reason. I would suggest running the Blizzard app as Admin to help make sure those settings are saved.
