Hi Senines, We appreciate you reaching out to us. We’d like to gather additional details that may help us be in a better position to assist you.

Have you had the chance to try a different app that allows you to draw or take handwritten notes?

If yes, are you experiencing the same issue with a different app?

In the meantime, let’s check for a software update and make sure that you are running the latest version of iPadOS.

While it isn't inherently assured that an update will resolve the issue, updating to the latest software version for your device can help isolate potential software issues. 

Kindly secure a backup and update.
