I'm having the same issue. Can type a new note and can save it by going back (mgs pops up saying do you want to save), but that's it. Can't edit note again, can't change anything. All options we need is now too high on the screen to use as its behind battery, signal and other icons on top and bottom of the screen. 

**WORK AROUND**

rotate phone to landscape mode!! I can access relevant options to save, edit etc! 

Its not ideal - but it's an improvement of what I can do in portrait mode!! 

I have the same issue with a Pixel 9 pro. However, changing to the landscape mode does not fix the problem. I am unable to search or edit. These issues make this app unusable for me. Please reply with a corrective action I can take. Thank you! 

This issue is now fixed.
