Cant login since 1.12.1 update

Minecraft was functioning normally prior the latest 1.12.1 update.

 

Now I simply cant play in multiplayer because Im unable to login: When I click on the login button, the green screen appears with endlessly rolling circle and thats it.

 

On another phone, same model but little bit different software due to different region, pressing the button leads to login screen, where after filling login and password game says that it was unable login due to unknown error.

 

Reinstalling the game didnt help.

Phone model: Pocophone F1
