Hearthstone Mobile App Won't Link Account

Hi there,

I previously played the game on mobile, linked an existing battle.net account, and bought packs (whizbang expansion).

Now it won’t let me relink, I keep getting directed to login at battle.net, I do so, and then it just stays in battlenet with no redirection, and no login to the hearthstone app.

I wanted to play the game again, and honestly would buy packs but the fact that the last 100$ I spent has just vanished is gonna make me not play the game / if I do, I won’t purchase anything for sure (why would I when the last purchases I made have now vanished?)

Any help with this issue? I have redownloaded the app and tried to sign in multiple times.

Thank you!
