I am logged into my FF account of a laptop, tablet, phone, and desktop. All of them sync settings and open tabs without any trouble except for my phone (Android, Pixel 7a). I can only get the phone to sync tabs by logging out and logging back in. This has been an issue for months, but previously it would work if I restarted FF (or sometimes when I restarted my phone). It now only works by logging out and then back in. What's odd is that it appears to still sync my search history. I could be mistaken, but sometimes when I visit a new tab it appears that the same url will autocomplete when I am on my laptop. But, the tab being open on my phone does not appear in the "Show tabs from other devices" or "View recent browsing across windows and devices" areas.
