ODST free? Clarity needed.

Downloaded MCC on Dec 3 2019. No Gold or GamePass, ODST showing up in the store with message saying “You can use Halo 3: ODST or buy it to own.” and the Install button is there. Reach has no message on the store and only the buy button.

I’m getting some mixed messages. It was my understanding that ODST is included free with MCC now, is that true? I even thought that new downloads were including Reach too.

Really appreciate some clarity. Thanks very much!

New info. Installed ODST, went back to campaign menu, and it still brings up the go to store and buy ODST box when trying to start campaign.
