iCloud not syncing
I am in the cloud with iPhones and one Macbook Air and they are all up-to-date. My Mac is not syncing with iPhone and neither is iCloud online. I only noticed it with one Contact which is missing from Mac and when I go online to iCloud but it is on the iPhones. I also just tested it by adding a new contact to iPhone but that too does not show on Mac or online.
I signed out of iCloud on Mac, turned Mac off, rebooted, and signed in but it did not help. I am afraid to do the same on iPhones in case I lose them.
Any ideas?
iPhone 11 Pro, iOS 15
