Old iPhone iCloud tabs show up in Mac Safari
Consistently, very old iPhone iCloud tabs are showing up in my Safari (macOS Catalina). I try to get rid of them but very soon they show up again.
Here is my setup: iPad Pro (running latest iPad OS), iPhone 12 (running latest iOS), MacBook Pro (running Catalina).
The problem only appears on the Mac Safari. That is where the very old iCloud tabs for the iPhone show up. To note, the iCloud tabs for the iPad when displayed on the Mac Safari are correct and current.
The problem does NOT show up on the iPad Safari. All iCloud tabs of both the iPhone and Mac that are showing on the iPad Safari are correct and current.
How do I solve this problem? I have already turned on and off Safari syncing on the Mac. I have tried to delete cookies, websites, and preferences. I have even go so far as to try to locate the Preferences file in the Mac Library from the Finder and delete them.
What else can I try?
MacBook Pro 13″, macOS 10.15
