App does not work at all

It keeps saying to connect to my device via Bluetooth..but I am already connected and streaming music to it!!

Then I wont connect or show any wifi, it stays hung searching for one. Even though my phone is connected to wifi.

Then, when I try to share my wifi settings from my phone, nothing happens.

So the app does not work at all. Clearly, this is an app developed by a one-man team, designed by the developer maybe. Cannot compete with sonos.
