WTH is going on with the sideboards?? PLS FIX IT.. what about going into events?

Bo3 Sideboards through multiple Formats dont work normally.. Reinstall doesnt work.. Some said building up Decks from the scratch worked for them but sadly not for me.. so cmon wizards.. are you reading this anyway?

Playing on IOS. During deckbuilding, I noticed I cannot add cards to my sideboard if I have 4 of the same card between Maindeck and Sideboard. Once I remove the 4th copy, I can then add them into the Sideboard.

One workaround is to have 3 copies of one card and then you can add them to your Sideboard. After this step, you can then add the 4th into your Maindeck from your collection, but this 4th copy cannot be added to your Sideboard.

For me this happens consistently if my tablet shuts down because of no battery. I plug it right again, turn it back open, open the app and my game resumes. At this point, the game is broken and I wont be able to sideboard any cards, and also cant send reactions to opponent (like “Hello!”)

How is this not fixed yet? I play best of 3 because I enjoy sideboarding, but I just played a BO3 explorer match and could not sideboard. So frustrating

This has been happening to me on macOS, Windows and iOS. When the bug has happened I tried rejoining the match in progress from another OS but the bug was still there

This just happened to me on Android as well. I could not interact with the sideboard at all.

This keeps happening to me on my phone, I’m so close to mythic and I keep losing because of this

Dude. Seriously you are a billion dollar company. FIX THIS DADDY HASBRO. Good lord.

I played a best of three standard match and I could not sideboard any cards in, after removing cards from my deck to add sideboards it refused to add them and stated deck was invalid.

This just happened to me in a standard event. We went 3 games and in game 2 and 3 I could not sideboard any cards. It would remove cards if I clicked the "minus" button, but I couldn't put anything back into the deck. I had to wait until the clock ran out and it autosubmitted the original decklist. Playing on Macbook pro.

This happens literally every game to me on PC. I guess I'll stop playing on arena again...

I am having this issue on both my Android Samsung phone and on a Windows PC, with MTG Arena downloaded through steam.

This is happening to me right now. I tried closing the game and client multiple times but nothing is helping. I am on OS Sonoma 14.5

I keep having the same problem on my pc. Once i sideboard cards and click ready to play, the sideboard system crash and makes me wait until i finish the 2 minutes for the sideboarding time. After the two minutes end i can finally start game 2 but no card of the deck is actually changed. This problem has been the same for couple of months now. Please fix it asap

I can’t sideboarding

I had the same issue today and lost because of this, I am using an ipad to play the game, please fix it.

I keep running into this SAME issue it has literally cost me games because I cannot sideboard in the proper cards. PLEASE FIX THIS!!!!

I saw this issue too playing BO3 ranked Explorer on client version
2024.42.10.1781.1099041
I'm playing on an iPhone SE 2020.

During sideboarding phase of the game, I can remove cards from my deck. But tapping cards in my sideboard does not add them into the deck.
I have not found a way to add cards back to the deck.

This problem persists, causing a lot of losses, please resolve.

Happening to me on both an iPad and a Mac, being able to play BO3 is pretty essential with RCQ season being standard next.
