Hi, I had an unstabled system for a few months, that required repeated Windows reinstalls. FINALLY tracked down the issue, and now I'm trying to recover all those old tabs. I was making SOME progress, with my last two installs as well as two devices I'm currently using showing and me opening synced tabs laboriously one at a time, over and over, so I could eventually filter through all the doubles and triples and quadruples of tabs that were opened over the last few months. But starting today or yesterday, the Synced Tabs sidebar is no longer showing those last two installs, only my current two, even though those last two - and many others - are still showing in my Connected Devices. Did I reach some auto-cutoff date for Sync storing them? Or does it still have them and I just need to change a setting somewhere?

Thanks for any help you can give, and I DO have a tab backup system, it's just... imperfect. Still working the kinks out of it, so I was hoping to use old Synced tabs to fill in the gaps.
