Thank you for posting back and for providing additional information.
The issue might also be related to the device itself since it happened after you updated it. However, before we consider that, have you tried adding a different note to your device's home screen? If so, does the issue occur? In addition, if you have a different
app that you can use to take notes, I advise adding it to the home screen and see if you will still experience the same issue. I also suggest checking if there are updates available for the OneNote app, if so, please update it. If that doesn't work, then the
issue might be with the device itself.
Feel free to post back should you need further assistance.
