Hi Mosinathus,
First, thank you for the quick response.
Update on the issue:
after viewing this post: https://us.forums.blizzard.com/en/hearthstone/t/stuck-at-tavern-doors-android/42618/10
I ignored the prompt to search google drive for progress at login and signed in with my Blizzard info instead. (regular blizz username & Password)
It worked, the game started normally on my phone.
However, I wish to make sure that bypassing hearthstone’s connection to my google drive does not harm my progress / experience in any way.
From what I can tell, nothing seems to have changed - my account and progress are fine and synced on both PC and mobile.
I wonder - what is the purpose or benefit of linking HS to Google drive?
