iCloud tabs not syncing/working

iCloud tabs stopped working on my iPhone 12 Pro Max after a did a reset (erasing all content and settings) and restored from an iCloud backup. Since then, I cannot get it to work again, even after following the advice here and elsewhere. As a recent Android switcher, it means I need to go back to Google Chrome until this is resolved, which kinda sucks (I prefer Safari's privacy consciousness). I cannot live without this feature.

I have a second appointment with apple support at monday.

He wants to install a "new profile" and get some systemlogs from my macbook again.

So in the end he's trying to get this issue fixed.

i told him some days ago about the missing icloud tabs setting on the startpage, too

i will keep you updated.

Thanks Martin, very helpful.

I'm adding a bit of info, if helpful. Yesterday I bought a brand new iPhone 12 Pro. Same issue, I see no other tabs under Safari (while it was working fine on iPad + old iPhone). Mac stopped working mid November, no way to get it back (I changed PC and upgraded to Big Sur in the meanwhile).

It took 3 days but it finally came visible on iPhone. It took only short time for iPad and Mac (not upgraded to Big Sur). The iCloud backup never pulled in the last state of safari with the tabs I had. This was first time doing restore for iCloud. Normally I do the direct transfer option but the apple store / genius desk person refused to let me do it with the screen damaged (but perfectly operational phone). I could have just stepped aside for 15 mins to do it but they refused. Since iCloud backup was deficient and staff policy are inflexible, I got what I got and learn lesson

Same.

iPhone 12 Pro, iMac, MacBook Air - all on Big Sur / iOS 14. All up to date.

No safari tabs but......

Safari history works. Each device can see the other's history..... Bizarre....

Crickets from Apple.

same here. everything else works perfectly with iCloud. There are a ton of macrumour's website readers with same problem. I've wiped both my iPhones, iPad, and MacBook and no luck..Cleared all website cache, website data, turned safari iCloud off on all devices and deleted data, rebooted, turned back on...It's def. a server side issue, IMHO. Too many having the same problem. There's not many iPhone related troubleshooting I haven't figured out in the since 2007, but this one I haven't.

It worked, until I used the MBP. I think most users are not affected if they don't own a MacOS device, that's my theory right now. I stopped using the MBP for a week and disabled Safari synced tabs and everything worked flawlessly between iPad and iPhone.

I suggest at least you try disabling safari in iCloud on MacOS and see if that fixes sync between any other devices you have (it may take a day or two). By no means is this a solution, but I mainly use chrome on desktop and as default browser, I can rely on continuity from my iOS Safari.

Second appointment done:

We installed a new profile called "CloudKit" on iPhone and Mac and then run some diagnostic tools on iPhone and Mac and sended them to Apple.

So we have to wait, but still they want to fix this issue.

Keep you updated!

Just noticed my new iPhone (the one i added before noticing issues with Safari's tabs) does not have Hand-off between the iPhone -> iPad. Macbook ->iPhone & iPad -> iPhone & iPhone ->Macbook works, but not from the iPad to the iPhone. Neither Universal Clipboard. Seems im having some kind of iCloud's Key exchange problem

I have the same problems that iCloud tabs are not shown in safari on my Mac. Also tried unchecking the Safari Box in iCloud settings but didn't work.

Interestingly iCloud tabs work perfect on my iPhone and iPad Pro. Only the Mac has the problem.

iCloud tabs on my devices have been messed up for at least six weeks. I installed 14.3 on my iPad Pro and SE2 yesterday. After I rebooted, all the tabs disappeared. This afternoon, I saw them reappear on my SE. Yay, I thought. Maybe this is fixed. Alas, they've reappeared, but are more messed up than ever. I have tabs going back months. The ONLY iCloud tab field that's correct is the one on my iMac (10.15.3) pointing back to my iPad.

UPDATE: As I was typing this, iCloud tabs just vanished from my iPad.

Clearly, something is broken.

And yes, I tried all the "things" ... rebooting, signing out, reset network settings, etc ...

It turns out that Apple engineers have released the ones that should be beta in a corrupt way without testing some improvements again at the product level. This bullshit is getting too annoying. Especially macOS and Macbook Pro. I am having the same and multiple problems. They do not respond to feedback and are not interested.

Did that and rebooted the phone...no tabs.

interestingly however, the Siri Suggestions on the phone show the current webpage I'm viewing on the Mac...which happens to be this very page. Not the same as iCloud tabs though....

Mine have come back but the tabs showing on my iPad for my phone date back to November! (Tabs since closed on phone). Notes stopped syncing last week, and my safari bookmarks are also not syncing between devices.

Tabs will automatically disappear after 7 days by default.

You can also delete a tab from another device by swiping it left. The latter one is handy for getting rid of tabs that have suddenly appeared for some unknown reason from months ago.
