Dialog cut off one Phantom?

[SivertUhre]

But it seems to be the Dialog, not the speaker when the problem went over to the other speaker after I change the left and right setup in the spark app?

Do you know any other way of troubleshooting the problem?

How are the speakers connected to the Dialog? Via PLC, ethernet or WiFi? Are both Phantoms connected the same way? Does the problem still occur when you connect the Phantoms  and Dialog to the same power strip?

It says PLC for some reason, never WiFi. I will try connect it to the same strip, see if that helps
