Latest upgrade took my entire system offline

I bought a Sonos Sub Mini (received yesterday) and when I went to add it, the system forced an upgrade. The upgrade took forever and after I got that done 30ish minutes - I added the sub.

After the upgrade my old Beam/SL 1s went offline and disappeared. I then tried to do a Advanced TruePlay for the living room (Arc Ultra/ 2 300s/sub mini) and it keeps failing. I tried doing a fast true play and it too is failing. WTF Sonos? Your upgrades are absolute shit.

Anyone else having issues and how to fix? I might as well return the sub mini at this point. What an embarrassment of a company.
