I am unable to send picture messages and receive "Can't send message right now. There are too many unsent multimedia messages." I tried to upload pictures to print thru the Walgreens app, after becoming frustrated with the application I canceled the upload. I've been having trouble sending messages ever since. I've tried to clear all running applications in the Task Manager, and checked the Multimedia message limit through my Messaging Settings and increased the limit. I can't figure out how to clear the unsent multimedia messages, can anyone help? Thanks!
