S50 Pro+ Tidal stops working

I have had this problem with Tidal HiFi, when I play any song it plays for 2-3 seconds, then stops and plays again. Usually just before the end of a song it glitches for a fraction of a second and starts playing again. On other days a song can stop 5 to 7 times for 5 - 10 seconds. I use fiberwire internet 300Mb, the device is connected to WiFi, the strenght of the signal always above 81%. These stops are so annoying that you can’t listen to it. When I stream Spotify or internet radio it works perfectly and much faster. Does S50Pro+ have a problem playing higher resolutions and bigger files? I have up to date firmware, 4stream is also up to date. I reset the device many times, deleted unnecessary data from the aplication, changed WiFi from 2,4 to 5 Ghz nothing works.
