Vlad I want to try a new profile however it doesn't seem possible to enable iCloud sync on a new profile. I made a new one and set it as the default, but moving the sync preference over to it isn't happening or available.
With my existing iCloud sync profile I have been experimenting with how the sync might break. It has taken a lot of back and forth between my 3 Macs, iPhone and iPad to ensure all tabs are closed in each tab group (I called them workspaces earlier). To do so I would go through each tab group one device at a time making sure Orion is closed on all others. Quite often long closed sets of tabs would reappear, along with entire tab groups I had deleted in the process. After about 3 or more rounds of closing tabs and tab groups across all devices everything appears to be closed and not returning.
In this process of cleaning up my tabs I found that when I got to the 4th or 5th of my devices they would have an old copy of the synced tab groups. When the tab groups would open the old set of 40+ tabs would remain on the device and thus load them back up into iCloud to then show up on all of the devices where they had been closed and synced.
With a seeminly clean tab & tab group slate I would open two devices to the same tab group and watch as a new empty tab would open on one device and automatically pop up on the other. I'd visit unique sites on each tab and watch as the other device would do the same close to instantly, though not all of the time. On occasion a new tab or change of a tab wouldn't sync instantly. In those unpredictable events a stray tab would be on one device, but not another. I could move on to creating new tabs and they would sync across devices instantly. Unfortunately like the bug title says, it seems to be unpredictable.
