You may want to log in to the Sonos.com website with your account, and make sure that the location is set up for your account still. Sonos uses that in some cases to “filter” what is presented to you as accessible in the Sonos controller. And your street address isn’t important, I think it’s just country and maybe zip/post code, although I can’t swear to that.
However, if all that is fine, there’s a couple more steps I’d try. First, of course, is a simple reboot of your router, followed by a reboot of the device you’re running the controller on. It’s always possible there’s a memory issue, or a caching issue that could be causing the issue. Shoot, as long as we’re reloading software, try a reboot of your Sonos devices, by unplugging them from the wall for a minute. They might benefit from a reload of the software running them as well.
However, if none of that works, I would recommend that you submit a system diagnostic , and call Sonos Support to discuss it. Most people respond better to not being cursed at, if I interpret the moderator edit above, even if it is frustrating to you, which I suspect it really is.
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the phone folks, there are more options available beyond just the diagnostic analysis.
