After last update (to ver 16.4.4288) I cant get past the loading screen with the inn doors and the pulsating HS logo and HEARTHSTONE word.
I play exclusively on my Samsung S7 android phone.
After initial contact with support through GooglePlayStore from where I downloaded the app, I tried uninstalling the app reinstalling. Restarted both phone and app before that, and restarted phone again after reinstalling for good measure.
Previously I just got stuck at the loadscreen, but after reinstalling I got prompted to tap screen, and the asked to sign up or sign in. Tapped Sign In and got to “check for stored progress on google account”. I hit Yes and selected my google account.
At this point I was ultimately back where I started, at the aforementioned inn doors loadingscreen. No change, even after many many minutes of waiting. Might be that this connection was the problem all along, or it just stuck at visually the same point even though the backend problem changed after reinstalling.
Only thing I can think of except the obvious that a bug came with the latest update is that we created a “family account” on google to manage kid screentime. I would assume that its not related, but worth mentioning.
Is there any other info I can contribute with to help with bugsearching?
Best regards

Update
Tried with selecting No when prompted to check google account for progress, just to see what happens. I got in! Everything seems to work, and I DO even have all my decks and everything.
Must be some kind of bug still though, because I got extra packs for “welcome back” like I did a while back when I started playing again after a longer period without. Strange, but if thats the only bug Im currently experiencing Im not complaining 
Still downloading something in the background now (the “last 1.0 GB” whatever that contains) so we’ll see what happens when everything is done.
If I run into anything else I will post it here.
My quests seem to have reset, but other than that everything seems to work normally. Really strange, but Im happy again ^^
