I also can't sideboard in Bo3, PC and Android. It doesn't go to the sideboard deck manager screen, just straight to waiting for opponent. I've lost 2 matches in Ranked this way.

I am also unable to sideboard on iOS in Explorer BO3 matches in both ladder games and constructed event matches. I have submitted a ticket with more details (4179117) but basically, when side boarding with a phoenix list (Jengantha companion), the screen fades to black, fades back in, and then screen controls become unresponsive. I need to restart the game but once it's in that state I am unable to board at all and must proceede to the match. Same thing happens after g2.

Cannot sideboard after disconnecting.

The sideboard is still nonfunctional in ranked matches, even on windows desktop. Issue persists after restarting the client.

After the last patch, there are still problems with sideboarding. Usually happens on game three of BO3 matches, only tested in explorer since it’s my main format at the moment.

This is happening on iOS, app version 2024.39.10.1524.1084013

Sideboarding is broken on the iOS app. I can remove cards from my deck but cannot add others back in.

Arena can not count to 16. This screenshot shows that in the deck editor I have 16 cards in the sideboard, but only 7 are displayed.

unable to sideboard

is there a workaround? unable to sideboard

I wait forever after side board ad nothign happens, No matter the format, I basically cant play bo3 as a result. Help me please?

This problem doesn't seem to be fixed. Also, every sideboarding sees me waiting for my opponent for 90+ minutes all the time which I don't think is normal for all my opponents.

Bug still not fixed companion Keruga

Otra partida de evento estándar perdida porque no puedo banquillear después de la primera partida, es lamentable lleva meses este problema

Es lamentable el oro que estoy perdiendo por los bugs del juego a la hora de banquillear. Lleva meses este problema y nos capaces de arreglarlo. Es el 5º bug que reporto y no he recibido una mísera respuesta. Me dan ganas de borrar el juego

When I am playing a ranked best of 3 game, after the first one when I side cards into my deck, the game makes me confirm the changes and wait out the remaining time but when I'm actually playing the second game of 3 the changes I made are reverted. After the second game when I can side again the deck has the same cards it had in the first game and when I change cards the same thing happens: the game makes me save the changes to my deck, wait out the remaining time but in the actual match my deck has only the original cards and the side cards aren't present.
If a possible used italian language it would be better.

This happened to me twice now in a tranditional standard ranked game (see screenshot and log)

Same thing. Sideboarding with Obsosh as companion and none of my sideboard cards are coming up game 2 or 3. This is happening in direct challenge as well

Same issue! Game 2 always doesn't sideboard. Sometimes Game 3 does but my last few games also saw game 3 not sideboarded.

Yeah got the same issue side boarded cards out and in only to find the card i sideboarded out are not in my deck 2nd or 3rd game and the cards i sideboarded in are not.
