Sling may get much better after a visit to my internet provider's office. My "old" modem was slow and now the new one has changed the speed test from 21Mbps to 66Mbps.I think it is the app and how it works with windows 10. Amazon and Netflix are their own apps, and they work perfectly on my Xbox S, where the Sling TV app cuts out, hangs, gives me the spinning orange arrow, a LOT.
