Purchased New Sony 65" TV model # K65XR80 4K OLED Google. I can pair the ROKU remote (4k streaming stick and remote); however, the remote unpairs when the TV is turned off (for about 5 to 10 minutes). I have to use the Sony remote to turn the TV back on, at which time the ROKU remote will automatically re pair and control the Sony TV, including the Roku power off feature. The Roku remote will then be able to turn the TV on and off. However, once I power the TV off using the ROKU remote and leave idle for the 5 to ten minutes, it unpairs. Thoughts? It is as if the ROKU remote goes into hibernation
