iOS 18 Safari tabs not syncing via iCloud

I'm just adding to the chorus. Same issue. I did the 'turn them off and on again' thing and they all updated, but then everything just stuck on the newer version. According to iCloud Safari tabs, nothing has closed or opened since this reset several weeks ago, which is not the case. Based on my experiences, it would mean repeating the initial turn it on and off again across devices every time you want a current version of your tabs, and providing you never want any new additions you're set... which sort of defeats the whole idea.

I discovered a way to get at least some improvement to sycing. On my iPhone, I went to Settings, then my Apple Account, then iCloud then iCloud Storage. I found two lines for saved Safari data, which seemed odd. One was 400KB, the other about 800KB. Anyway, 1) turned off iCloud Tabs and Safari syncing to iCloud on both my iPhone and iPad. 2) I deleted both Safari lines from iCloud storage. Restarted my devices, turned everything back on. Now it seems to sync when I force close Safari on both devices, which is an improvement. But still not fast and automatic like it was back in iOS 17. I also notice that Safari no longer shows up in my iCloud storage, so I think that continues to be an indication that something underlying is still broken.

Yep, same issue here as of 3/5/25 (iPhone 15 Pro Max - iOS 18.3.1) it’s like the sync is delayed by 24-36+ hours or something.

Same issue here, works fine on iPhone but won’t show up on iPad at all. Tried resync on iCloud (turn off and on), tried force reset devices, restart Safari, turn on and off iCloud tabs etc.
