This has been one that has bugged me for a while, but just now getting around to filing it.
I use an iPad Pro with the keyboard attached. When I do my reviews the the answer field is blocked by the auto completion / language selection bar from iPadOS. I can swipe it to the side to get it out of the way, but I feel like there must be a way to account for that bar being there and slide the answer field up in that scenario.
