To revert back to the original method of sending notes, you can try a few steps. First, ensure that your notes are being synced properly between your Mac and iPhone. Make sure that iCloud sync is enabled for Notes on both devices and that they are logged into the same iCloud account.
Next, check the formatting of your notes on your Mac before sending them to ensure they appear as intended. Sometimes, formatting changes or inconsistencies can occur when copying and pasting text between different applications or devices. Make sure that the text is formatted correctly and that any special characters or formatting are preserved.
If the issue persists, you may want to try sending the notes using a different method or app. Instead of using AirDrop, you could try sending the notes via email or messaging apps like iMessage or WhatsApp. This can sometimes help preserve the formatting and presentation of the notes better than AirDrop.
Additionally, if you're still having trouble, it may be helpful to reach out to Official Apple Support for further assistance. They can provide more personalized support and guidance based on your specific situation and may be able to offer additional troubleshooting steps or solutions to help you revert back to the original method of sending notes.
