if photos upload automatically to the photo stream, why do I have twice as many photos on my photo stream. It seems also to have stopped uploading photos in early March. I also have 2 photo streams on my ipad (which is synced to my phone & computer); one with 400+ photos & one with 200+ photos. I ipad also has only 300 of the 600 original photos in the camera roll.
If your device has stopped adding photos to photo stream, save any photo stream photos that you want to keep on your device to the camera roll, then turn photo stream off (which will delete the photo stream photos from your device) and back on. That may get photo stream to function properly again.
