I have that really annoying issue with my Destkop-App. Everytime I start the App, I close WoW (any version) or be idle for about 10 mins+ I cant click play, because the game needs an update. Always. 24/7. It takes 20-60 seconds and i can hit play. Game files and battlnet files are both on external ssd. No other Destkop-App has this issue, Steam etc. everything is fine (also all on external ssd). So far i tried reinstalling app / games,app beta mode, admin-mode, clearing reg, playing with 0 addons, the list goes on. Everything i can find on forums etc. didnt work so far. Im open for new ideas, because this is so annoying. I cant figure out what it is. If I start the game from directory without the app, 0 issues. But ofc i have to manualy login in the game then.
This also happens with every game on the app. Overwatch, Hearthstone, Diablo etc.
