I have an Album "1963" on my mac. It contains multiple pictures. When I click Share, View in Browser - the browser screen states "There are no photos in this Album". All of the rest of my Albums display correctly.
I have worked around the Bug. I created a new Album '1962', imported the images again into '1962', removed all images from '1963', deleted '1963', & then renamed Album '1962' to '1963'. On my wife's Mac she can now see the images in '1963'.
