Hello JSW52,
Thanks for posting in the Apple Support Communities. We're happy to look into this with you.
We were able to test this using the steps below, and it worked with not issues.
- Open the email you want to save as a Note
- Tap the arrow at the bottom of the screen and select Print
- Tap the Share icon at the top of the screen (next to Print)
- Select Notes
- Type in a name for the new note you're creating
If that isn't working for you, check to make sure the iPadOS is up-to-date in Settings > General > About. If it's not, create a backup and install the update.
