I am trying to set up two Sonos Era 100 speakers using the new Sonos app (dark background), but both are showing the following error during the registration process:

“There was a problem setting up. Our customer support team is ready to help.”

I have already tried the following steps:

• Performed a full factory reset on both speakers (green flashing light).
• Restarted my router and mobile phone.
• Attempted to set up one speaker at a time.
• Confirmed that my phone is connected to the same 2.4GHz Wi-Fi network.
• I’m using only the new Sonos app and have uninstalled the S1 app.

Unfortunately, none of these steps have solved the issue. The speakers still appear as “Not registered” in the app. I suspect they may be associated with another Sonos account or there may be a firmware issue.

I kindly request:

• Support to unlock or manually register the speakers.
• Confirmation of whether there are any additional limitations I should be aware of.
