Updating S1/S2 compatible products

If you’ve previously updated the from S1 to S2, it’s done. Or, are you saying you can’t update to the latest version of S2?

That is correct. I can’t update to the S2 app, though I have been able to do so in the past. 

That’s odd. What error are you getting when you attempt to update? Which controller device are you using? What OS is it running? 

In general, any device that has been running S2 shouldn’t have any issues updating to the latest version. There may be something blocking the ability of either your speakers, or your controller from reaching the Sonos update servers. Possibilities include VPNs, work profiles, virus protection apps, pretty much anything that may self update (so you’re not aware of a change) and block the ports that Sonos uses to update. But that’s conjecture, the answers to the questions above may point somewhere else. 

I don’t get an error code when I try to update a speaker. It just doesn’t update. I don’t have a controller, so the OS of the controller is irrelevant. It’s a pretty basic system, which is why this is so distressing. Nothing is blocking me from reaching the servers. No VPN, no work profile, no virus protection apps, etc.
