Safari Tech Preview 126 - Tab groups not saved/synced

Unfortunately this makes them rather useless for me for now as my lovely curated groups all disappear on exit :-(

I get it's good to get the idea out there for devs to test, so maybe the rest isn't ready yet, but a release note reference would have helped if so.

I confirm that saving tab groups does not work on STP 126 in Big Sur. Actually, this is main reason for me to use new Safari. Please fix this problem.

I also submitted feedback to this effect.

Equally, I don't seem to be able to open bookmark folders as tab groups, which I was hoping would be an adequate interim work around.

Can't even pin tabs anymore, so hopefully it's just an early preview oversight?

I've just tried STP 127 hoping this might be fixed - but now I can't see tab groups at all - indeed other design changes found in 126 appear to have gone

I installed the Monterey Public Beta today and the tab groups are working for me in that environment, but still not in Big Sur.

I also have updated today to 127 on Big Sur and don't see any sign of Tab Groups there.

The release notes for STP 127 and STP 128 explicitly say:

Note: Tab Groups do not sync in this release.

The release notes of the latest STP 129 don't note anything regarding Tab Groups, but considering they're not syncing I would assume that this simply has not been implemented yet.

For anyone coming from Google, as of the release version (Version 15.0 (16612.1.29.41.4, 16612)), Tab Groups still do not sync reliably and they randomly disappear, so don't invest too much time creating them because they'll just go away at a moment's notice.

Tab Groups disappeared on Safari Quit. I spent 4 hours organizing Tab Groups and they just disappeared. This means the open tabs I had converted to Tab Groups are now gone, vanished.

Fortunately, I used SessionRestore macOS app and have retained my original tabs, but I will have to start over again and reorganize. This is likely 8 hours lost.

This was NOT a beta version > Safari Public Release Version 15.0 (16612.1.29.41.4, 16612)

Wanted to confirm this problem still persists in the final public release.

The problem is still present in Safari Version 15.0 (16612.1.29.41.4, 16612)

But with a twist... between my iOS and iPadOS devices the tab groups get synced perfectly. All groups, all tabs, nice.

On the macOS version Safari there is only one tab group (the first one on my other devices) and it contains only one website. So.. some kind of sync is happening obviously.. not to one we are expecting though.

Unchecking / checking Safari in my iCloud account settings results in the same tab group with only one website in it..

At least my iOS / iPadOS devices don't care about the Macs and keep all the tab groups + websites. Won't use Safari on Mac until this is fixed I guess..

I can confirm this. Safari Version 15.0 (16612.1.29.41.4, 16612) It is an erratic behaviour because I was able to save 4 tab groups and those are still being saved when I make changes to them. However, any new tab group I create is gone after closing Safari. Additionally I have noticed that there is often a Safari window 'Untitled' that is visible from the Window menu but not accessible.

I actually have the opposite issue: I've created several tab groups during Monterey beta and now those tab groups and the tabs within them are stuck in that initial version and I cannot update them anymore. I close a tab and quit Safari, next time I open it it's back where it was. I move tabs into the default tab group (did this with all tab groups), next time I start Safari the tab groups are back there, closed tabs reappear, newly opened tabs disappear. I cannot get Safari to save the tab and tab group setup no matter what - tried deleting cookies, history, local storage...

I just noticed the same problem is still present on macOS 12.0.1 with Safari Version 15.1 (17612.2.9.1.20).

I have the same issue, if I delete a tab group on safari 15.2 (17612.3.6.1.6) on macOS 12.1 , It immediately sync back. It also shows up 2 times.. so I have for example 2 folders with the same content. Tried removing them both first the first secondly the second, all syncs back. No clue which is the master. Should try to do it on my iPad or iPhone and see what the outcome is on that.
