I find the pencil tilt only works in one direction, I think this is a bug. When you angle the Apple Pencil, the pencil line should get thicker like a real pencil does on paper. This only works in Fresco in one direction; I have to rotate the paper 90 degrees to get a thicker line. This isn't how it's supposed to work. It's the angle of the pencil that matters, not the direction of the paper.
im using the first generation pencil and a 2nd Gen 12.9 iPad Pro.
Update: just checked this on procreate and the tilt works properly, so it's not a hardware or general iPad problem. Must be fresco. I'm sure it used to work normally otherwise I would have noticed sooner. It's a real issue as it affects my entire workflow. It's like drawing with a broken pencil!
Sorry about this. We're aware of the issue and are releasing a fix for it in the next update, which should be available in just a few days.
Keep an eye out for that update in the AppStore.
Tilt doesn't work at all. Newest iPad Pro and newest pencil. Just downloaded Fresco recently.
I'm still having this issue, just as described by OP.
Using the current latest iPad Pro, and latest Apple Pencil. But it was also happening on my second gen iPad Pro and gen 1 Apple Pencil.
