so I used to be able to drag and drop photos into my chat box and it would open the photo sharing window and a thumbnail of the picture would appear in the chat saying I'd shared it. last night it stopped working. I would send a picture and the photo sharing box would open to me and my friend but it would say loading and no thumbnail would show up. after 20 minutes of waiting, it still didn't send. I reopened the window and tried again, no luck. I reinstalled messenger twice, tried two different versions of it, even downloaded the portable version and it still doesn't work. her computer worked fine, she could send pictures to me and I'd receive them fine. I'm not signed in anywhere else, I haven't changed any settings and I'm really confused as to why this has stopped so suddenly. please help, it's so annoying
