Hello again with an update...
No one called me back at my scheduled time, so after about 20 minutes of waiting I called myself 1-800-275-2273 and asked for a Senior Advisor (mostly because I already had a case number and knew it needed to be escalated).
I got a Senior Advisor who was awesome (Thanks Brenda!). She completely understood the nuance of this issue and didn't make me jump through a bunch of hoops, mostly because I described a bunch of different things I had already tried.
While we were talking she must have been looking through cases and she eventually found one that was the same issue. The notes on that one said to do these steps:
- Turn off Shared Albums on the device you are uploading from.
- Wait until all the Shared Albums clear.
- Wait another 10 minutes (this was emphasized).
- Restart the device.
- Turn back on Shared Albums
- Wait until all the albums and photos in them reappear
Can you see the portrait photos now?
In my case the answer was no. In fact, since this is the device I was uploading them from, I had been able to seem them there before turning off Shared Albums, and now I couldn't. I also tried sharing a new portrait photo to that album to see if it was fixed going forward, but no, same problem. I can see it on the device, but no other device can.
So she took a bunch of notes and escalated it to engineering and will get back to me next Saturday and I will let her know if it just magically fixes in the mean time.
Again, I highly recommend taking the time to message or call (ask for a Senior Advisor LOL) so they understand it's effecting everyone. I've tried posting portrait photos to Shared Albums from multiple devices (iPad, Mac Mini m1, MacBook, iPhone 13 Pro, iPhone 12 Pro, iPhone X) and can not ever get it to work. Well, with one exception, if I take a portrait photo of a non-person (i.e. dog, cat, object), then it works fine. 🤷♀️
