All of the sudden, I cannot send any photos through the gmail app. The email hangs up in the outbox folder saying "sending" and never clears. Tried playing with the number of pics, same issue from 4 to 1. I went to settings > manage applications and cleared data for gmail app, this worked for a minute, I could send test emails of just text. When I attempt to attach pics again and send, same issue occurs. This seemed to pop up out of no where, I could send pics before today without issue. Also, this happened while I was out of house on LTE, and when I got home on my WIfi, same issue occurs so it doesnt seem to be a connection issue. Anyone know what the issue is or what I am missing? Thanks in advance for any help.
