Thank God, with His help and yours, and alot of trial and error, it is "sorted out", this is what I did: Having only my Apple TV+ Subscription, I googled up, "iTunes [store]" and signed in with my present Account, it scanned my system and I found where it found my A/V Receiver and my LG OLED Model and my Computer. I decided to not gamble too much $ in order to see if using the store I could rent/buy a Movie and see if it would be sent to my TV+ APP, Halleluia it was. I then ran into a new problem to solve: that AppleTV APP is located on my Nvidia Shield and I could not get it to play, it would start and then stop and tell me to check my Internet Connection, I did than and rebooted my N. Shield to NO avail. Then it dawned on me, I have installed the A. TV+ on the LG TV too, I should try playing that same .99 Movie straight to and thru my HDTV in stead of using my streaming device: WALA! Success! Hope this might help someone else that might be dealing with same or similar problem.
