I'm using photo app from iPad. It seems like if you save the picture as image from facebook web site (not the facebook app from iPad) it will hit by this issue. However, iPad2 work well for both channel (app and web site facebook). Btw, i have 2 iPad at home each with difference model.
I have noticed if the photo taken by myself or picture save as photo from facebook for both channel it will work well. Is this a bug on new iPad ?
