"Notes disappeared after accepting iCloud T&Cs on iPhone: I just clicked to accept the new iCloud Ts&Cs and ALL 722 of my Notes have disappeared. I can see them on my iPad but they have GONE from my phone. I am frantic. I use the Notes all the time. Please help?"

Troubleshooting Syncing iPhone Notes:
A. Start Here: If you're Missing Notes on your iPhone, iPad, or iPod touch - Apple Support
B. Sync Through iCloud:
Look in iCloud settings or preferences on each device, and make sure that Notes is enabled. If it already is enabled, then disable Notes, and then enable Notes. See what happens when you open them on that device.
