I want to make sure that you are able to use the app you prefer for texting, cmlevy. I am sorry that your contact with our support team was not able to resolve this concern. Let's look into what is happening. Is the app up to date on the most recent software? I know you mentioned that this is happening with one person. Does this happen with other contacts as well? Does your phone still alert you that a text message was received from these contacts? When did this issue begin? What changes were made prior to this issue beginning?
