Photo Won't Attach to Text or iMessage
I've noticed in the last week or so that all of my photos that I take with my iPhone camera are no longer staying on my phone and being uploaded to my iCloud however my phone is not keeping the original - when I go to look at a photo it will not load unless I have data turned on or there is a tiny exclamation point on the right hand side of the image. This has only started happening recently, however I have not changed any settings on my iPhone, Macbook, or iPad recently.
Also I can receive MMS messages, but when I go to attach the photo to a message (normal text or iMessage) it allows me to select the photo but does not attach. I have tried both ways of attaching from the message, or going to the photo and selecting share > message without success.
Details:
iOS: 9.3.2
Settings > Photos & Camera
iCloud photo library ON
Optimize iPhone storage ON
Upload to my Photo Stream ON
iCloud Photo Sharing ON
Settings > Messages
MMS Messaging ON
Any information or ideas would greatly be appreciated!!
