Notes not syncing from iPhone 14 pro max to my iPad

If Notes are not synchronising between your iPad and iPhone, ensure that both are signed-in to iCloud with the same AppleID - and you have enabled iCloud Notes on both devices:

Settings > [Your Name / AppleID] > iCloud > [Apps Using iCloud] Show All > Notes - set to ON

i've experienced if 1 device had a really old ios version then the notes format stopped being compatible and would not sync
