Message as a ghost message
On my IPad only( nothing on my IPhone) indicates a unread message. I have read all of my messages, and even deleted all of my messages and still one message shows are unread . I have checked the unknown senders list too.
I have looked into a blocked number, removed all the blocked numbers. Turned app off, and back on. Turned IPad off and on. Still the ghost message appears. Any suggestions??
