My 2nd pack choice was ultron then it glitched out and won’t let me beyond this page or reset for new packs

Exact same problem here. Jump in Marvel. After choosing 2nd pack, was kicked out of screen. WHen choose Jump in marvel again, 1st packet is chosen but no choices for 2nd pack on screen and 'confirm pick' button grayed out ie cant be clicked. Basically, Jump in Marvel is broken for me.

Too bad bc jump in is the best especially the new style of marvel jump in. PLease fix soon.

Same here, playing version 2026.60.20.13374.1294424 on Steam (machine is Ubuntu 24).
Managed to play once, it was fun, so paid again 1000 coins, picked first pack ("Lethal", for whatever it matters), picked the second one, validated and ppof back to the main scene. Wehn I go back, now I have the first pack selected, but no second packs proposals to choose from. Clicked everywhere, back, Enter, ... nothing works, it's stuck with my 1000 coins gone and no cards and no fun (the worse).

Same issue here, marvel jump-in is now unplayable because of this exact issue. I can’t submit my own bug report either because of how bad your system is. My platform is iOS, my packs were agents of shield and counter argument. After picking the second pack it spit me back to the menu and now says choose packets but agents of shield is greyed out, counterargument is missing, and there are no packs to choose from and no way to fix it. Already tried your auto-repair and it did nothing. Congrats on making a jump-in that was already a pretty low-value proposition for those who don’t play brawl into something that’s just straight up broken now.
