Can't share photos
Have created 'Shared' Albums, and tried numerous ways to add photos, nothing works.
Out of 40 photos, 5 did make it to a shared album, but we didn't do anything special, they just made it while others don't.
We tried icon in the upper right to do 'iCloud Photo Sharing', which creates an empty 'Shared' Album, but never one with photos.
We tried 'drag and drop' in to these empty 'shared' albums, and see a little clock spin in the upper left, but then nothings.
We tried 'Add photos and videos' in the shared albums upper left, nothing worked. Besides that is awful method, since it doesn't show the albums we already created that we wanted to share.
At the higher level, the process is confusing. We created an album of photos we wanted to share. Would prefer just marking the album as 'share'. Appears we have to recreate the entire album, and isn't easy to associate the two.
