Mobile upload problem

[Mindy5767]

I hope this is the right forum for this question because I can't imagine where else to ask it. When we're at Disney, one of my favorite things to do is mobile upload pics on the spot to my facebook profile. Sometimes I like to take a really cropped pic and see if anyone can guess where I am. I do this all the time and never had a problem. Yesterday, I tried to mobile upload a photo and it didn't work. I tried it three times. Never showed up. I used both the weird email address version and the 5 digit number both of which previously worked to upload the photo to my facebook profile. I have a Samsung Reality phone. With my upcoming trips, I'm really worried that I won't be able to do this upload anymore. This will take away so much fun. Does anyone know how to fix this problem?
