I have problem with in-game currency on PC and PS5. My coins are loading endlessly with a loading triple dot. I logged out and in. Deleted all settings and files related to the game.
Nothing helped. This happened after the start of the current season.
same for me, in addition vc doesn’t work(error 5027)
Deleting Battle.Net helped me. Don’t forget files in
C:\ProgramData\Blizzard Entertainment
C:\ProgramData\Battle.net_components
After reinstalling Battle.Net, authorization issues in-game disappeared and I could use Shop and see coins again.
Haven’t hepled me 
I’m sorry to hear that. Just today, I had to repeat this procedure to restore proper authentication in OW. This accompanying “Agent” process works for about a week in my case, before it goes back to not functioning properly.
