HELP ME PLEASE! XBOX ONE BACKWARDS COMPATIBILITY NOT WORKING AT ALL?!?!?!!?!?!?

Whenever I put in an BACKWARDS COMPATIBLE GAME into my Xbox One S, NOTHING HAPPENS! I don't get any notification, update and the Xbox acts like nothing is in the DISC DRIVE!!!!

What the [Mod Removed - Profanity]?!?!?! I have 120+ GB of space, and I have the PHYSICAL DISCS of the BACKWARDS COMPATIBLE GAMES. WHY THE [Mod Removed - Profanity] ISN'T IT WORKING?!!?!?!?!?

When I go to the store, and go to the page of the BACKWARDS COMPATIBLE GAME 'Call Of Duty Black Ops 2', it says "See Price" despite me already owning it Physically! Then it asks me to BUY it?!?!? AND GUESS WHAT? ALL the DLC I purchased on Xbox 360 can be
downloaded to Xbox One, but NOT THE [Mod Removed - Profanity] GAME?!!!!!!!!!?!?!?!

SOMEONE HELP ME FOR CRYING OUT LOUD, XBOX ONE BACKWARDS COMPATIBILITY DOES NOT WORK FOR ME

I have tried:

-Restarting the Xbox One multiple times, both with the Backwards Compatible game inside the Xbox, and outside.

-Turning the Xbox one completely off multiple times with the Backwards compatible Disc inside and outside the Xbox

-Un-installing MULTIPLE of my games in order to acquire space for the Downloads (that I never even got!)

-Following instructions from the Xbox One forums and Troubleshooting (totally useless)

-Following guides from YouTube and other media (Totally useless too)

-Using the Xbox assist and Help options on Xbox

-Changing settings on Xbox One

Things that may be helpful:

-I have 'Xbox Game Pass Ultimate' and it IS still in effect

-I have not Reset my Xbox (Never going to delete my data)

-Digitally owned Backwards Compatible games work fine, but Disc owned games do not

-NOTHING happens when I enter the Discs

-I have an Xbox One S

BACKWARDS COMPATIBLE DISCS I HAVE:

-Call Of Duty Black Ops 2

-GTA IV Episodes from Liberty City

-Call Of Duty World At War

-Call Of Duty Black Ops

YES THESE ARE ALL BACKWARDS COMPATIBLE I HAVE CHECKED MULTIPLE TIMES!

PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
