iCloud tabs not syncing/working

Did anyone get this resolved? It's May 15, 2021.

I have not.

Your issue sounds like mine, except that it's my MBP tabs showing on my iPad and not deleting or updating.

I'm so glad that worked for you! Unfortunately, it didn't for me, but the Apple engineers are working hard .... :)

Everybody should check their Safari tabs. Mine are working for the first time in over a half a year.

I can't decide whether to be happy that I was not the only one to suffer from this, or to facepalm at the very thing happening to people in the first place...

Anyways, I also tried everything to fix my iPhone Xs MAX and iPad Pro (1) combo starting about 16 hours ago from writing this, and like @(Bernard Desgagné) said, it seemed to be gone until I found out 8 hours later that it does update, in an outrageous time lag...!

So after some help from the local Apple help phone service, I tried the following recommended steps in order;

1) turning Safari exempt from my iCloud connection temporarily,

2) blowing up all my cookies and web data for Safari,

3) resetting network settings (+ the automated reboot)

...as of writing this now, the iCloud tabs are gone again. Who knows, maybe it would update hours later? (sarcasm)

I'm having the same issue.. my MBP is running Big Sur, my iPhone XS is on iOS 13.5, iCloud tabs are not synchronizing at all. Will probably call Apple Support later this week if the issue doesn't resolve.

Bump. Had the same issue just today.

Using iMac 2019 27" w/ Big Sur and iPhone 12 mini w/ iOS 14.2.1.

Was working just fine earlier today, but after I unchecked the "iCloud Tabs" checkbox once on my iMac, it just disappeared completely(no any option and checkbox in Safari app) and not showing ever again.

Have tried toggling "Safari" option bar on/off in the iCloud tab on both my iMac and iPhone.

Also tried sign out/sign in my Apple ID and iCloud account on both devices.

Neither of above worked.

Hopefully, Apple would fix this soon :(

Same here BUT they were working with Big Sur (upgrade from Catalina) and new iPhone 12 until a few days ago. Had general iCloud and even Finder challenges and sent all of it to Apple Engineering. Right now I have no tabs in Safari Mac despite signing in/out of iCloud, turning off Safari iCloud sync (it takes 2 clicks now to get it to turn on). There must be some bug.

Just to let people know - I too have the issue and spoke to an Apple Tech this morning after two Chats last night,

Like most of you I have toggled safari on and off, restarted devices, signed in and out of iCloud, tested in Safe mode - all to no avail. Like some, this morning I woke up and Tabs on my iPad were there, but out of date, from before I upgraded to Big Sur, but the moment I went to the MacBook and opened safari, they disappeared. Tabs on my iPhone are correctly showing pages I opened on my iPad - and no tabs whatsoever show up on my MacBook. The one thing I did discover through the chat is that if I open the history on my MacBook, tabs I have open on my phone and iPad ARE listed. (Photos and music are syncing and bookmarks are also syncing. However:

TL; DR - the tech told me after a lot of troubleshooting and doing a Screen Share that I/we are not alone, it is a known issue and they are working on a fix. He said to keep checking for updates. The one weird thing is that when he looked at my iCloud info, it was showing tabs from 2019 - but none that are active today. He said it's something to do with the way the new Safari is passing Tab info to iCloud. Weirdly it's all fine for my husband on the same network with an iMac, iPhone 11 Pro and iPad Air. I have an iPhone SE 2020, MacBook and iPad mini. I think all we can do is wait - I feel better knowing that they have acknowledged it's a problem.

I'm facing very similar issues using iCloud Tabs. But it's kind of weird on my side. Running a MacBookPro (Big Sur) and iPhone 7 (iOS14.2) iCloud Tabs do appear only within certain networks. At home is does not work at all. Neither creating a hot spot WLAN with my iPhone nor using my router's WLAN. In the office everything is fine both using Hotspot WLAN and using office WLAN. I have tested to create new Favorites in Safari. They do appear on all devices after some seconds in all configurations (Home WLAN, HotSpot, Office WLAN). So it seems to be an iCloud Tab issue only! iCloud Sync does work at least for favorites.

Any ideas?

My tabs also have stopped syncing. I have an iPad Gen 6, iPad Air 2020, iPhone XR All with the latest 14.3 iOS, and Late 2012 iMac Running Catalina 10.15.7. I believe that because I pay for the iCloud service that I should get more support that none whatsoever. This problem needs to be resolved.

What we are experiencing will not be helped by Apple’s page telling us what to do if tabs are not syncing. We have all tried the steps recommended by Apple.

further back in this thread many fixes have been suggested, but none work.

Indeed, this is becoming quite annoying after more than a month. I was told that the issue would be solved with "the next update". There has just been an update, and the problem is still there. Hopefully, someone in Cupertino is reading this thread.

And I have tried all of the steps. I’ve even restored my iPhone recently for another issue and that didn’t help. Most of the time my devices don’t show any tabs open on other devices. Or if they do show some, they are from a few days before.

I tried calling Apple on this issue yesterday and was put on hold. After about 10 minutes I was disconnected and they never bothered to cal me back 😡
