Why does sync break EVERY week on my phone. EVERY week I have to spend half an hour trying and usually failing to get my phone to be able to receive tabs from my desktop computers. Why do you break this critical feature with every update no matter how large.

I restart both firefox on all my devices as well as the devices themselves. I clear cache, cookies and even do fresh installs. Nothing works until a day or so later it magically deigns to function again.
