I just bought an ipad pro since I was having issues with palm rejection while drawing on desktop with a wacom cintiq 27q hd. (It was detecting a point on my palm while drawing with brush tool and was making zig-zagged lines even when I have the gloves on and I wasn't really having an issue beforehand like years ago using the earlier versions of illustrator cc.) But I'm really disappointed with the ipad version as well. There are no problems with the glove on but w/o it whenever my palm touches the screen first it does a pinch of zoom. It's probably about the shape of my palm when I'm holding the pen there happens a little bump resembling a point of finger therefore detected as one. I have skinny hands so. It doesn’t happen when my gf uses it because her palm is smoother while holding the pen. At least that's what I'm thinking the issue is all about. I've seen many posts regarding this issue so it's more like an adaptation issue with slightly different anatomies of a hand. So maybe implementing something like palm rejection radius as in z brush would be a better solution. I hope it gets worked on. Thanks in advance. And yes, this happens even when the palm rejection is on. Forgot to mention.
