I came across an issue yesterday when messaging one of my contacts on bb messenger. When sending a message to a certain contact it has the D next to it and when the contact reads it and responds to my message it will still have a D next to it instead of the R. It also says the contact is busy all the time. I have no other problem when messaging any other contact on my list. i have tried renaming the contact and even re adding. Is there a way to fix this problem?
