Well, I figured out the problem with Tidal and my home network. My comcast xfinity router is set to block ICMP as a standard security setting. When I allow for external ICMP, Tidal on the AK380 works. However, my iPhone and Mac OS Tidal apps work fine while ICMP is blocked. It's only AK380 that won't work. I unfortunately don't have another Android device to compare. I did get some support responses from AK so I sent them this information and will see what they say. I am also going to consult with some IT friends to see if there are any risks with enabling ICMP.
