Que hacer para recuperar notas de mi iphone? Tenia cerca de 20 notas y de un dia para otro solo aparecieron 5

Hey there wpaez7,

Thanks for reaching out to Apple Support Communities. I understand that your notes go missing from your iPhone unexpectedly. I’ll be happy to help.

To verify, when you say they disappear from one day to another, do they return at all and disappear again?

In most cases, you should be able to recover your notes on your iPhone using the steps here:

There is also some steps that you can take to recover your notes from iCloud.com that may help as well. This article has more info:

If your notes continue to go missing after you recover them, you may want to check your iPhone storage and make sure you have plenty of space:
