iOS 9.3.1 Cannot add pictures to iCloud shared album
Ever since upgrading to iOS 9.3.1 I cannot add pictures to iCloud shared albums.
Have tried this two ways. By selecting pictures from camera roll and selecting iCloud photo sharing option. If a new album name is set, the album is created but it stays empty. The second way is going to an iCloud shared album and try to insert a picture by tapping the +. Nothing happens.
I've also noticed that even recently taken pictures are being loaded from the iCloud when viewed(I have iCloud Photo Library enabled). Before this update only older pictures were downloaded when viewed and recently added remained on the phone/ipad.
This is happening on both my iPhone 6 and iPad Air 2 64gb each and there is plenty of space available on them both so it shouldn't upload recent pictures to photo library and delete from phone straightaway.
Any known issues?
