Not coming through for me, just a Do Not Enter sign.
Got both this morning, but now only R. Pleasing enough.
Hard to know. They were up for a while, but then disappeared.
Did you create a new folder in Google Photos? If so, you might need to set the permission so that it's publicly viewable.
Looks like the missing step was that I had just added the photos to the shared album I set up for AP posts, but then I had to go to each photo and confirm that I really wanted to add it to the shared album. A bit strange, but seems to work.
Yep, I see them now. Very nice.
