I am having a similiar problem, not sure where to post it. Here is what is happening:
1. Take a photo with iPhone 4
2. Syncs to great up until last night
3. Last night I brought a photo into Nik's Snapseed app on my iPad (import from Photostream)
4. Now, my synced Photostream shows up on my Iphone 4, iPhoto, but the Photostream album on my iPad shows no photos.
5. However, the photos are there on the iPad, because if I use a photo editor app and import (again, like Snapseed), the photos are there and I can import. But the Apple's Photo app the album shows no photos.
Very strange....I think this has to be a bug.
Apple really needs to think about real use of Photostream. The concept is great...but I have to admit it is buggy. Adobe Carousel app, when it is released, looks ideal.
Apple, why can we not delete 1 photo (rather than the whole Photostream)?
Apple, is this a bug that we cannot import into other apps because it then blanks out our Photostream?
Apple, why do new photos from my Camera app go to my camera roll and Photostream...workflow of editing and sharing photos is very messy this way with duplicate photos.
I am not sure how I am suppose to get my photostream to show up again on my iPad. I have tried resetting my photostream, hard reset my iPad, nothing works.
