Why is this app still a pile of steaming sh !t?

Open app.

Please enter 2fa code.

Game missing.

Close app (menu-exit)

Open app.

Enter username/email.

Enter password.

Enter 2fa.

Game now reappeared.

And this while I have 'Remember This Device' ticked.

Isn't this supposed to be a multi billion dollar company?

(And this is not the first time this has happened)
