This is a really annoying bug in Windows Phone 8. The Facebook photo albums in the Photos hub will only load the first 100 photos. I uploaded over 400 photos to one album and I've gotten hundreds of likes and comments all of which show up in the Notifications tab of the me tile, but when I tap on one and it's related to a photo that is NOT within the first 100, the photo that it is related to will flash for a second and then go back to the 100th photo in the album. I can't read comments on photos at all.
Also, if I set the album cover to an image that is not within the first 100 of an album, the album shows as black in the Windows Phone 8 photos hub. Not cool.
SkyDrive photo albums do not have this limitation problem. Please fix!
