I have an issue with Roku 3800x Streaming Plus stick 9.1.0 build 4111-55. The "Play on Roku" media player works for one song maybe 2 then stops. Also photo player runs for about 3-6 minutes then stops. Only way to get it working again is to totally restart the Roku remote app. Using an Iphone 7 with on version 12.3.1. So all latest versions but it doesn't work! (note Iphone remote says connected to Roku stick)
Could it be Iphone goes into some kinda sleep mode even though program is running????
