Hi all. I am having a seemingly unresolvable problem with my samsung galaxy ace on snapchat. I am getting the message "sorry, this video cannot be played" for 99% of vids I receive. Now I have taken the following steps in a failed attempt to resolve the issue - downloaded MX media player - set this as the default video player - cleared the snapchat cache - restarted the phone. All this to no avail. Can anyone shed any further light?
