Yes I'm using the preloaded Tidal App, I was playing MQA tracks.
i had the same issue with my Kann Alpha when using the preloaded Tidal app. a 3-minute song would play, for example, until around 2 minutes 15 seconds, and then abruptly stop and move on to the next song. very disruptive.
i then loaded the full Tidal app and it's been working fine. i wonder if there's some incompatibility between the preloaded, non-full fledged Tidal app and the Tidal streaming? Who knows?
why don't you try to load the full Tidal app and see if it works as well for you as it has for me?
