Hi, i also encountered this problem. I maked sure the cloud driver on ios and macOS is open and same account is logged in. But just some notes are synced on my iphone and mac, when i updated note on my iphone, it does not appear on my mac. In addition, the context updated on my mac also can not sync to my iphone.
Therefore, partial content is respectively on mac and iphone.
Can you give me some help?
