Same issue. Password is the same and working perfectly fine here. Just the MTGA client. Very frustrated as it's going to make me lose an arena run.

Same, “Authentication failed for ‘username.’ Unable to login, IOS

Having the same issue on iPad

All users are affected but this issue on all platforms. However, you can manually update on Windows. Ok Android, you cannot manually update to 2021.7.0 from 2021.5.61. When trying to login it fails to authenticate, regardless of the network connection we use.

Trying to log in on iPad running iOS 14.6. Program displays "Unable to Login, authentication failed" message and sends me back to login page.

On IOS and having same issue

no puede ingresar

Cannot log in it shows message:
Autentication Failed
What is going on?

Cannot login on iPhone after update, authentication failed.
Cannot login on PC after update, stuck on Loading Initial Scene.

Since all existing options are non-functional after this latest update it would be nice to see some sort of compensation from Wizards for lost time and progress due to downtime.
The day a new set launches is a terrible day for downtime on all devices Arena is available on.
Very unfortunate that always seems to be the days that the software becomes inoperable on every platform.

I won't be holding my breath for any compensation either.

Same issue. Tried logging in on the computer and have no issue there.

Since the AFR update I cannot enter the game, the massage that pop is: authentication failed for my account

So, the Forgotten Realms update has been applied, and now I can't log in. It keeps telling me "Authentication Failed". I have logged out and tried my account info again and it says the same thing. I have tried reconnecting, nothing.

I have attatched my software information so someone can diagnose it further. I am currently using a Samsung Galaxy s20 Ultra 5g.

No I have not tried logging in on the computer. I'm still at work and can't download it.

cant login. says authentication failed. playing on google pixel 3 .

Same as above

I'm assuming it may be server issues with this new D&D set coming out on arena. <really high traffic on servers?>
