One of the cameras I use on a regular basis is the EOS 90D. I have noticed something on more than one occasion that I don't understand. When using the camera in AI servo I almost always use the middle expansion area which consists of 9 focusing points. When shooting in landscape orientation I can see them in the viewfinder. If I switch to portrait orientation I can only get 1 center spot. Is that the way it is supposed to work? Thanks.
There is some sort of setup in the menu where you can program different "focus patterns" depending upon camera orientation. Check to see if that's enabled.
If you want to keep it enabled, simply hold the camera in the vertical orientation and change the focus pattern to whatever you prefer, same as the horizontal orientation or different.
I experimented with using this on previous models, thought it slowed down AF a little, so I disabled it. Having different patterns depending upon orientation also meant setting them up two or three times, any time I wanted to make changes (once for the horizontal orientation, again for the vertical orientation with the grip at the bottom, and I think a third setup for the vert orientation with the grip at the top).
My cameras... not 90D, but other models with the same function... are set to use the same pattern regardless of orientation. It's faster, easier and I really saw no need or value to have the pattern change depending upon orientation. But, that's just me. It may be different for other folks.

Check page 565 of the EOS 90D manual and Custom Function II - 10 for linking the AF point based on the camera orientation.
Yep, that's it.
It's a little misleading because it not only effects AF point selection, it also effects AF pattern selection. When you enable different selections depending upon orientation, you can not only utilize different AF points, you also can choose different AF patterns. And, if I remember correctly (since I've made a point of NOT using it for many years), there are actually three possible orientations... one horizontal/landscape and two vertical/portrait, as described above.

Yes, this is a feature on the 1Dx2.... I guess it has migrated to at least the camera body the OP has too now.
The 7D-series cameras have it, too... Both the 19-point AF system on the original 7D and the 65-point AF system on the 7DII.
I don't know about the other cameras with 61-point, 45-point, 19-point AF systems.
