I have owned and used Poly for 3 weeks now. I was initially confused by Poly’s hot spot mode and wondered how I can stream Qobuz or Tidal on the go if my phone connects to Poly as a router but without internet connection. poly’s hot spot mode appears to serve the sole purpose of playing back music in the SD card on the go. Later on I realized that in the opposite by turning on my phone‘s hot spot and letting Poly connect to it can not only stream Qobuz from the phone app to Poly, but also create/maintain the uPnP/DLNA connection so that I can play back high res files stored in the SD card in Poly, without switching modes in GoFigure app. It works perfectly and stably, so now I wonder why bother to use Poly’s hot spot mode. Therefore, what you asked is absolutely the way to go. Happy listening
