Safari Bookmarks/Reading List/Tabs not Syncing

I have an iPhone 11 Pro (iOS 13.2.2) and 2019 MacBook Pro (MacOS 10.14.6). They're on the same iCloud account, and Safari syncing is turned on on both devices. Handoff works, as does syncing of calendar/reminders/contacts.

However, my Safari bookmarks, Reading List, and open tabs do not sync between the two devices.

Has anyone else had this issue? I can't find anything on Google... I've signed out of iCloud on both devices, restarted them, etc.

Thanks everyone.
