So after years of not playing for various reasons, I found the e-mail offering 150 free packs and decided to finally update the game and try again.
Unfortunately, the game has so far only allowed me to do two things: I was able to open all my packs, and I was able to view the new achievement journal and earn some of those rewards.
If I try to go into My Collection, it shuts off immediately.
If I try to go into the Shop, it shuts off immediately.
If I try to browse the Solo Adventures menu, it shuts off immediately.
And most importantly, if I try to start a match in any mode (I tried Mercenaries and Casual Hearthstone), it shuts off immediately.
I have restarted my phone.
I have restarted the game.
I have cleared the cache.
I have cleared the data.
I have uninstalled and reinstalled the game.
None of these have fixed the issue.
I’ve been at this for about seven hours total, maybe six if you don’t count successfully opening the packs, though the achievements were done while waiting for a download to finish.
