I may be onto something here. I was thinking long and hard about what I did to the iPad or pencil when I had the pencil start to skip. There was two: I updated the iOS version and I took the pencil tip off and put it back on. Even though I’ve already tried tightening the tip, I thought maybe it’s not tight enough and it has to be cranked to hell and back. So I really cranked it yesterday as hard as I could with all my strength using a a tool with a towel wrapped around it so it doesn’t damage the tip. I just need to give it more time but so far it hasn’t skipped.I don’t doubt it was some software change but it doesn’t seem to be affecting a wide group of users which is truly bad for your case. Like I said, it sucks but I have no advice. You’ve already done everything I would do in your situation. Sorry I can’t be of more help.
These pencils are poorly made. The tips come off way too easy and who in the engineering team thought it was a great idea to have a gap between the tip and pencil so dirt can get inside? Surface pen is how it should be made so that the tip can’t be removed and no gap or evem loosening of the tip. Apple just designed it this way so they could make extra money from us having to replace the tips every month?
