Apple notes on iPadOS16 lags until stops working.

Hello

I have been using my iPad Pro (11 inch) for over 2 years now mostly for taking notes. I have been using the default Notes app along with the apple pencil for this purpose.

Up until now I had no problems, but after updating to iPadOS16 the Notes app started to malfunction.

Whenever I write on a note for longer than ~10 min the iPad starts to heat up a lot and the writing starts to lag. If I keep writing despite not being able to see what I write because of the delay, at some point the app just crashes and what I just wrote dissapears from the note.

I have noticed that even if there is considerable lag, if I create a new different note the problem goes away. Also, I have another notes app that does not have the same problem, so I figured there must be a problem with software. What should I do?

Thanks.
