After completing a match all the lower UI for daily quests, games, and mastery exp disappeared

Unable to Login - Authentic failed for "username"

saw some other people had this problem but no solutions, stuck at bronze rank 0 and no way to rank up. any updates to this problem?

I did today's update this morning and now I cannot play the game. I tried booting it up 5 different times and it just keeps giving me a black screen with the music and the cursor, but that is it. Can you please tell me how to fix it?

Both the Friends List and Daily Challenges disappeared from the homepage.

They were there when the update dropped but disappeared after claiming rewards from completing a few matches

I am unable to log in on both desktop and mobile. Whenever I try, I get "Unable to log in: Authentication failed for Let'sGetKraken: Attach failed to drop other attach". This has persisted for about 20 minutes now.

Bruenor Battlehammer ability is bugged, should be able to pay 0 to equip first piece of equipment, but since latest patch, have not been able to equip anything for 0, the ability to pay the regular cost is still there.

After the D&D update, everthing shakes when you drop a card, even lands, its kind of weird

Cannot login to the game, it just keeps sending me cycling me back to the login screen everytime.

I open the game and it downloads local files and then presents me with login screen - then I type in my password and it goes to download local files and presents me with the login screen again. Stuck in an endless loop unable to log in!

Can´t see the circles of the daily and weekly quests in the main screen.

I cannot start arena, i keep getting message that I lost connection to server, when I try to restart, I am logged off, but I cannot log in again (I immediately lose connection). My internet is working, server status according to the Status page is also fine. Connection lost appeared when I was in deckbuilder

The game is stuck after entering login and PW on requesting format data. Weird thing is that it happens both on my PC and on mobile.
Please help?

After the new update the challenges and the friends pop up don't appear, if I'm challenged there is an animation flame thing that appears, but if I go to click on it the flame disappears

Wont let me log in keep saying Authentaction Failed and I was logging in fine yesterday but had issue this morning so Uninstalled game on phone and PC and tried reinstalling and now I cant even log in

I'm in an infinite loop, I just login the application starts loading (gathering local files) and I'm again at the login screen.

If you have the same issue, create a new "post" and vote up all the other posts with the login issue!

It is simply ridiculous that on the "Server Status" page is everything "green"!

Al intentar entrar en el juego.. me dice que no puedo porque hay un error en la autentificacion de mi cuenta. Cambie la contraseña y sigue sin dejarme entrar al juego.
