I dont receive messages from blue doted contacts. There is a blue dot or others have called it a notification dot next to peoples pictures on my messaging app. I dont receive messages from those people until I send one. Then I get all their messages at once. Other contacts do not have dots and I receive messages right away. One blue dot is on the same phone plan and I do not revieve messages. There is another phone on my plan that I get messages right away. Please help me fix this!!!!!
