You are not reaching out to Apple here.
These are Apple supplied Apple customer/product user to user technical support/troubleshooting communities.
We are, largely, just Apple customers/product users, just like you!
I have never liked or trusted the Apple iOS Notes app as it has always, ALWAYS been glitchy and buggy and has always failed me when I tried to exclusively relied on it!
The iOS Notes app has never, EVER been a reliable and stable app.
Apple uses its iOS Notes app as more of a “showcase” app and Apple seems to never fully 100% realise this app!
Apple seems to always get this app to, like 80% to 85% “there” and that is as far as Apple ever gets their iOS Notes app!
In addition the Apple iOS Notes app ONLY gets updates and improvements and new features ONLY once a year with the introduction of a new iOS/iPadOS.
The iOS Notes app is NOT an app to be exclusively relied upon!
Free is not free if there is always a potential for the app to lose data.
If you really care about anything you write or do with your iPad, do yourself a HUGE kindness and purchase another more stable and reliable, third party notes/writing app.
There are plenty now compatible with the Apple Pencil.
These allow backup of your writing/notes app data to all data storage/backup services like, iCloud, Google Drive, DropBox, Box.
