There is an issue with proper syncing of Safari in iOS 13. For me two of my devices do not sync the other 2 do. So it can be specific to the device you have. If you were on a beta version you could submit a bug report through Feedback Assistant. I have. Hopefully this will be addressed in the near future.iPhone 10s Max bookmarks not syncing. iMac and iPad Pro are working good. Have tried all tips I can find on the web. Anyone else having this problem?
Must be a hell of a lot of challenged Apple IDs. This is a wide spread common bug.Solved: Contacted Apple Support and did all the recommended fixes to no avail. Passed on to tier 2 support and found that my Apple ID was showing "Challenged". This means that parts of the iCloud platform may be restricted. Support told me that they would clear it up and in 5-8 hours things should be back to normal. YES, all is working fine now.
When I first installed 13 on my 3rd gen 12.9 iPad Pro neither bookmarks nor history items synced to it. One or two updates later bookmarks started syncing properly but history items did not and still don’t in 13.3 beta. Signing out of icloud or toggling Safari off and on under icloud settings will force a sync and get everything on the same page but that won’t continue afterwards.I'm challenged too. My iOS 13 devices will sync bookmarks with each other, but my older iOS versions on 2 other devices now won't sync bookmarks with anything anymore.
Gotta love iCloud
