Can't start Entertainment from Hue Essentials

Hi, I’m new to DiyHue so bear with me.

I installed the Host version of DiyHue Master branch on a Raspberry Pi 3 and have the latest Hue Essentials 2.4.4 installed on Nvidia Shield.

I added the bridge plus my DIY gradient light strip to Hue Essentials along with an entertainment area selected, BUT, when I try to start the Sync entertainment program from the Android TV app, nothing happens. I press the button and there is no response to the button press.

I’ve tried all sorts of troubleshooting and simply now exhausted from trying so reaching out for some help.

I also contacted the Hue Essentials team about this and they said to take it up with DiyHue.

Thanks for any assistance someone can lend.
