Hey there Raid3n87,
Thanks for providing those additional details.
Just to clarify, when you say that you noticed that your notes were not syncing to iCloud, did you not have Notes enabled for any email accounts or iCloud in Settings > Notes > Accounts?
If you did not have any accounts enabled to sync your notes, did you by chance have the "On My iPad" Account enabled in Settings > Notes before enabling iCloud? If this setting was and is still enabled, try opening the Notes app, tap "Folder" in the top left corner of the display, and choose the Note's folder under "On My iPad" to see if the note appears there.
If you did have Notes in iCloud enabled, but the note disappeared after you started syncing your notes, then we'd recommend reaching out to Apple Support directly from this link here: Get Support
We hope that's able to help.
Have a great day!
