That seems odd, but I don’t have a Era 100 yet to test with. Have you called Sonos Support directly to discuss it?
When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.
Hi @sbm70
Welcome to the Sonos Community!
If your Sonos app is running on an iOS device, we are aware of an issue where several settings sliders are not operating as they should and we are working on a fix.
If you happen to have an Android device too, please adjust the settings on that in the meantime.
I hope this helps.
Hi @sbm70
We believe this issue to now be resolved with the most recent update (15.7). Please ensure your Sonos system is up to date.
If you still experience this issue, however, I’d encourage you get in touch with our technical support team to report as much. Thank you.
