Notes Not Syncing Between iPhone, iPad And Mac
Apple Notes App provides the option to store Notes on iCloud, which makes a Note created on iPhone to become available on your MacBook.
If this is not happening, the problem could be due to various reasons, ranging from your Apple ID not being recognized, iCloud Access being disabled for Notes App to other reasons.
In rare cases, the problem could be due to Apple Servers going through problems or the Notes App becoming damage or corrupted.
