An update started downloading, finished then said "almost done. Go to play store to finish" but nothing is there to update. I was literally playing 2 minutes before this and can't get in now.

Anyone else on android have this happen?

Blizz can be buggy. Try uninstall and reinstall.

My whole Blizz launcher on my desktop is bugged. I need to reformat as there's some driver errors which may be causing the issue, but after the most recent update to their launcher, I've had a lot of bugs: The launcher sometimes takes up to 2 minutes to load, sometimes it doesn't finish loading ever, sometimes it freezes randomly and has to be aborted, when I exit Hearthstone it freezes, and if I lag out of an Overwatch game the launcher takes 4+ minutes to restart.

Best solution: Reinstall, wipe any residual files on your phone/computer/tablet (whatever you're having issues with), just make sure you have your password/account/authenticator info retained.

Was about to try this because it seemed to be the only way, then the update magically showed up in the play store. I had been using Amazon play to get a discount on purchases but it took them so long to update i almost missed the promos for ungoro
