My Question or Issue

I stream over two devices - a Sony BluRay player at home and Ford Sync3 in my truck. On opening Spotify on my OnePlus at home the Sony BluRay is not recognized as a device, but after restarting my phone the Sony appears. On opening Spotify in my truck I receive a "no internet connection" message despite a strong LTE connection. Again, upon restarting the phone I am able to use Spotify. Pretty sure I should not have to restart my phone each time I use the Spotify app. Any suggestions?
