No sideboard when
1) I am disconnected
2) I have companion .In this case You must first remove the companion and then insert the cards

Please make the sideboard work. It breaks BO3

Couldn't sideboard in ranked after I got disconnected :(

This game sucks after the update. Can’t sideboard if you get disconnected which happens more and more.

JFC WotC it has been a month and this is still an issue. Not to mention some other fun and maybe related issues where both players are constantly being disconnected from the server and when reconnecting the client often just straight up freezes up and crashes. Every time I see the 'this weeks Arena update' post I always wonder if *any* of these critical issues will be fixed but they never are. Can you please squash some bugs?

Having same issue on PC, Explorer bo3 with companion. Cannot sideboard

Reporting the same problem on PC Windows 10. Fresh Install.

Experienced in Timeless Best of 3 and Explorer Best of 3. Both decks had a companion.

same on mac plz fix asap

Same problem, cannot sideboard after the update, was able to for the first 3 games, but now it's not working. If I uninstall and reinstall the client, then it works for a match, then the 2nd match the sideboard will NOT allow me to bring in any cards.

Please fix the bug.
MTG arena tends to harm the Magic: the Gathering brand reputation.

Can’t sideboard in timeless bo3 after game1 happened last season to

Let’s really get the ball rolling on this one…it’s pretty embarrassing that it’s still happening..

Could not sideboard in explorer. Using the arena app on iphone

Same issue can't sideboard after first round neither in second one
Bo1 is not fun and bo3 is unplayable because of this bug. Format timeless
Android Samsunga52s 5g

Issue for me too...

Same issue. On iOS (iPhone and iPad). If I DC or reconnect during a B03 match I am unable to sideboard after game 1 or game 2. Currently playing timeless format. Easily repeatable and super frustrating.

Couldn’t sideboard after game 2 in ios

This is also true when playing arena on android Pixel 8pro.

Hey, guess what, still can't sideboard, would love to play Magic the gathering on your client and maybe even spend money but I guess I'll PLAY SOMETHING ELSE

I also haven’t been able to sideboard since the last update. Makes BO3 pretty lame.
