Hi, I upgraded to IOS8.3 and the newest OSX. Now I am using the Icloud-Fotostream. Everything is working fine and I really like it ;-) Now I want to show someone a picture out of the Icloud Library, without having WiFi, but a working internet connection over 4G. If I tap on the picture, there is this small circle getting white on the bottom right corner. But it only fills to a quarter, then stopps and giving an exclamation mark. Further it is not possible to send an picture via email or imessage. There's this error message, which is saying, that something in the preparation went wrong and that I have to try it again later. Remarks: There is no problem using WiFi. I am using the space optimizing function. I already deactivated the Icloud-Fotolibrary and re-actived it. Is someone of you also having similar problems? Thanks for your help!
