From your feedback...

I tried Bluetooth connection on my iPhoneSE, streaming to the 210: it works, no problem.

Via Bluetooth, I successfully streamed Spotify and iTunes content from my iPhone. No problems encountered.

As for Wi-Fi streaming, you need a UPnP capable app - such as ‘mcontrol’ (free) on iOS or Android.
