Xbox Gold isn't enough to play online? "Missing privileges..."

So you were right and I had it all F'd up. Xbox finally got back to me a day later through Twitter/X and what I had purchased was "Game Pass Console" which I believed to be the same thing as Xbox Gold, not knowing at the time there was no longer Gold available but Core was the thing to get, and that when I saw the 'console' option -I thought I was getting the right one for my console since when I had 'Ultimate' before, its thing was 'you can play it on both your console and PC. So I was taking steps in the wrong direction. The rebranding of the names confused my GenXness.  Doesn't change the fact that when Battlefield was asking me to pick a play, 'Core' wasn't an option. It was 'Ultimate' or nothing. So I just bought a year Subscription to Core for my preferred price $59.95!! and I checked to make sure I could go online and it worked. Since you took such time to help me in the right direction, it behooved me to finish up my little emotional rollercoaster. Thanks again for all the assistance and patience. 😝 Seacrest, out!
