Large Hand Bug
When you have many cards in hand, Arena won’t allow you to scroll through them on IOS to let you get to the cards you need.
1. I used the -8 ability of Kasmina, Enigma Sage to tutor for Enter the Infinite, drawing my deck and putting a card on top.
2. iPad, IOS
3. Once my hand is full, whenever I tap on a card to try to drag it out, instead I can only access the middle of my hand, regardless of which card I clicked on. (This is in attempt to play Thassa’s Oracle and win)
4. When tapping on a part of my hand, even with a lot of cards in hand, I should be able to access that part of my hand and cast spells from it.

I have the same problem on Android with my grolnok, the omnivore deck. I wasn't having this problem a few months ago
