When I start the first tutorial battle, it stops after dealing me the first cards. After that I can't do anything

Is there any possibility to link PC and phone account?

16.07.2023, i couldn't connect to server, can't reach facebook page or customer service. glad i didn't buy anything from game, which i was planning today.

Have 5g home internet but game keeps saying check connection

I was upgrading the level of cards (Enchant Card option) and a white card with Chinese characters appeared, then the deck option stopped working and crashes the game. In Enchant Card menu i can't see any card.
