Log in on my phone to acrobat

Hello all,

I've tried to ask at support but no answer.

Every time i'm trying to download pdf files to my samsung galaxy note 10+ it's logging out of my account and when i'm trying to log in back in in able to read the file or edit it - he is logging me out and bring me back to the log screen.

Has somone faced this issue also and have a clue what to do?

It was ok till lately, maye an  app update or somthing interrupt?

Thx
