Conexión interrumpida, Imposible iniciar el juego, imposible iniciar partidas, imposible gestionar los mazos, ¡¡Gran actualización del juego!! ...

Had the same problem.
Setting the time-zone to (UTC+00:00) Sao Time fixed the problem for me. Just remeber that the time is no longer correct on your PC.
Still waiting for the fix, but is able to play.

hatte das selbe problem.
nach langen probieren hat das spiel dann eine datenreaparatur datei geladen ... jetzt komme ich gar nicht mehr zum schwarzen bildschirm, da das spiel jetzt beim laden der anfangssequenz stecken bleibt ... das leibt für stunden so ... bis die meldung kommt "verbindung verloren" ... dann kann ich mich wieder verbinden aber das spiel steckt noch immer
und keine hilfe zu finden .. im ganzen netz nicht

Same problem. Intializing game. Charging correct. I've tried the same in my PC Windows 10, on my iphone and tablet. Always the same. Then sound on, black screen, only the mouse pointer appears and nothing else I can do. I cannot play and it's anoying. I've tried to contact wizards support without an answer. Very bad service.

SOLVED APPLE DEVICE MTG ARENA MOBILE

Enter in game with login and password with UTC time zone => change UTC time zone on your general setting (DATE) to your time zone without closing the app. => logout and login with user and password without close the app MTG Arena mobile

Start the game -> black screen, sound on. nothing to do.

Please correct the "Trial of Colors" and it is impossible to enter the game for it. The game starts with a black screen and the game cursor playing music in the background, you can also hear the pressings. Partially solves the launch problem - only if you set the time zone to UTC-0.

Прошу исправьте "Испытание цветов" и за него невозможно зайти в игру. Игра запускается с черным экраном и игровым курсором, играющей на фоне музыкой, так же слышы нажатия. Частично решает проблему с запуском - только если поставить часовой пояс на UTC-0.

I have a black screen Issue after connection since this morning. Cannot log in. Can anyone solve this problem? I tried restarting my pc, reinstalling the game, opened another window to log out to previous acct, but nothing works so far. Thanks

Mismo error. Carga el juego, pantalla en negro, cursor y sonido están, pero aparece el mismo error de mehderard#79332
Llevo 3 días así. No puedo jugar, porque al momento de iniciar, aparece la famosa pantallita blanca con la "A" grande.
Nadie sabe que sucede, muy mal servicio.

I was getting this unity error occasionally since April. I've uninstalled the game with revo uninstaller and reinstalled it freshly. When I start the game it downloads about 4GB of data. Everything is okay until here. But when the game starts it crashes with this unity error.
I've looked on forums and I understand that it is something related with windows. I think it's Visual c++ or dotnet but I don't know how to fix or check it if I have problems with those.

While in the menu everything is ok but when match start the screen become black an mesage of "unit error" appears in the middle.

Can’t play at all on mobile. Match starts, unable to agree to mulligan or not…simply a black space instead. When game starts all cards I play have no graphics or abilities. Tried on pc and it works completely fine. iOS doesnt seem supported at all unfortunately and the game is unplayable on my phone. Please fix so I can play mtg on the go! Thank you. Update 6/20/21: game still unplayable on ios…unable to pick a hand, card graphics don’t appear. Will probably delete the app unfortunately.
