Hey, I also had the same problem, but it seems like in my situation it is fixed.
So, I kept changing my colour of the brush to black, and my apple pencil keeps not drawing anything
Then, there is the "main colour" button (shown in image) which I changed it to black afterwards and my apple pencil started drawing again - turns out it is a colour issue.
Old post, but still an issue. Tried all the recommended adjustments (restart iPad, restart Photoshop, uninstall and reinstall Pshop), but nothing worked. What I did find strange was that while my pencil worked in Fresco, Illustrator and Procreate, it was listed in my Blutooth queue as not connected after going back to Pshop. 'Forgot Device' and reconnected it and that finally worked. Hope this helps someone.
This may not affect most of the users here, but my iPad pencil stopped working and I was trying to find out why online. I did a simple restart of the app and it worked again.
If you are running into issues with Brush use with the pencil, is the issue with all brushes or only some of the preset brushes? If only with certain brushes does pressing harder with the pencil get marks made? We have had reports from a few users that pencil sensitivity is not soft enough. We are hoping to address this in a future release. Can folks running into problem go to preferences, enable Touch indicator in the Input section and make a screen recording of the issue you are seeing. (if unsure how to do a screen recording see https://support.apple.com/guide/ipad/take-a-screenshot-or-screen-recording-ipad08a40f3b/ipados)
I am encountering the second issue you describe above where in order to get a strroke to show up, I have to press down with a LOT of pressure (It feels like I am going to break my iPad/apple pencil!)...do you know if this issue has been resolved or will be resolved soon? Thank you.
Would you mind confirming the iPad and Apple Pencil version you are using? Also, is the application not registering any input using the Apple pencil or are you facing issues using the Apple pencil while using a brush/sketching?
I am using the Apple Pencil 2 and the 2018 iPad Pro iOS version 13.1.3. I can use the pencil to choose something in the toolbar a brush etc. but it does not register if I try and use that tool. Apple Pencil is working fine in all other apps. Procreate Pixelmator etc. As suggested I deleted the app and re-downloaded that has not solved the issue.
