Photos in albums showing on my devices but not on icloud.com
I have a few photo albums that are showing on the photos app on my ipad, iphone and Macbook but are not showing on icloud.com (tried Firefox, Edge and Safari).
In the online viewer, some albums show empty, on others the number of photos is correct but they are all shown as gray squares.
The pictures are in the cloud (I can see all of them in the Library).
Any ideas here?
