I am using it with a combination of iPad (4th generation) and ApplePencil (2nd generation).
There are some areas at the top of the screen that are difficult to respond to taps. This problem occurs almost every time.
The problematic areas are the Persona button at the top of the screen, the Back from Layer Options button This is where the It is very frequently used, but it is unresponsive and has a negative impact on productivity.
With the pen unresponsive, I can't see any response when I tap with my finger.
I went to the Apple store today to have my iPad and ApplePencil tested for this problem. I did. There was no problem with the results. Replacing it with another ApplePencil did not improve the problem.
There was no problem with the ApplePencil in other apps. I'm not sure if this is an issue with this app, but if so, I'm hoping for an improvement.
Thanks for a great app.
