P: Cannot use Pencil 2 on IPad Pro to use Mask/Brush.

For me the issue is solved. Just had to buy a new pencil 😞

Was this issue ever resolved? As of a few weeks ago, the brush masking has not been working in Lightroom on my iPad. I see this post is from 2021 but this is an issue for me now and I haven't come across an actual resolution for this yet when troubleshooting. 

Did you ever find a solution? I have the exact same issue you reported and using the latest updates of both LR and IPad OS on an IPad Pro 4th gen... so frustrating that everything works fine except the brush stroke.

Hi Paul, we weren't able to reproduce your issue with Apple pencil... are you still seeing that? We wonder if the issue happens during some unexpected double tap/ two finger tap, something like that? Also, it would be interesting to know if this always happens or only after a certain action.

Lightroom v7.1.1, iPad pro , Apple pencil II  IOS 15.2.1
When editing a mask using the pencil, after clicking "Done", lightroom does not restore the top menu. Both the cloud and export icons are missing and the help and menu (...) icons are present but inactive. They both change (shadow) when clicked but do nothing. 
The only way the restore the top menu bar is to exit the app and re-open it. 

However, if using your finger instead of the pencil it works fine. 
Apple has confirmed the pencil is functioning properly. 
I have removed and reinstalled lightroom as well as stopped and started the ipad. 

Both are up to date (LR and IPad). I've also replaced the pencil tip, to no avail.

@oeht , just to be clear, the update you tried was iPadOS 15.2.1 (and not just Lightroom 7.1.1)?  

@TaeAnnPhoto , can you also try updating to iOS 15.2.1 and let us know if that helps?

Lightroom developers cannot reproduce this, and wonder if this may be a hardware issue.  Apple Pencil tips do wear out.  If possible, please try a new Pencil tip, and let us know if that helps.

Did the update, unfortunately no improvement for me. Same issue still remains.

This bug was driving me crazy - but now good news. After updating PadOS to 15.2.1 the brush mask is now working correctly with Lightroom 7.1.1 and apple pencil 2. I guess it was something on the apple side.
