I have experienced this but I also found a solution! It was working fine for me on my home network but refused to play DSD while in Hotspot mode. I eventually looked up ‘chord.audio’ and got the IP address 192.168.1.1. I added this manually to Glider as an MPD server. All of a sudden I can play my DSD through the entry labeled [MPD] but not the one labeled [uPnP]. The problem could maybe be one of DNS resolution when the WiFi can resolve the name but the Phone connection cannot.
