The weird part about it is if you go to terraria itself on the App Store it won't let you download it at all. I remember when I was looking for solutions for this problem I saw a thread on here from 2019 (Mobile - How do i go back to 1.2 (iPad Mini 1)) with the exact same issue I was having.I’m really glad It worked out. I wish the game showed you the downgrade option, but this is a great outcome nonetheless.
