This, I believe, was what I had in the past. But some people disagreed with me that the process was instant/almost instant.I just wanted to say this for me, I’m the past, when it worked seamlessly, it was instant. You close a tab on your iPhone, it disappears from your Mac. You close that iPhone tab from your Mac, and that tab disappeared from my iPhone Safari browser.
Now it is different. Prior to Big Sur, among iOS 13 and Catalina it still worked but since I installed Big Sur, no syncing anymore. It doesn’t even show any iCloud tabs.
Do you think this problem is related to the operating system? Or is it a system side issue?
I believe it’s system-side issue cos it affects a wide range of operating systems across Mac & iOS devices.
