2020, You should get your Broadband checked, at my home I have almost zero issues with dropouts, listening to Tidal while writing this. At my office I have no issues on weekends and evenings but during the daytime its impossible to listen because of dropouts, I can speculate that its because of heavy data flow in our office building.
I think that the reason you have better luck with Spotify it because its not full format requiring less data flow, I'm sure folks more knowledgable on this subject can fill in on this.
Good Listening
