I had the same problem with my Node(latest version) as well but with Tidal MQA tracks. It was almost as if a switch was being turned off and on every other second. Non MQA was no issue. I’m using USB out to an external DAC. I was already an Amazon HD user and just trying out Tidal temporarily. I’m sure there was a simple fix but being the impatient old guy that I am I opted for canceling my Tidal subscription. I also had the Node 2i and could never get a higher sample rate than 44.1 using WiFi. Once I connected Ethernet directly to either old or new Node, I started getting the higher sample rates. Sorry I don’t have a solution for you..but I do have empathy
