I have a contact in Messenger that does not friend with me on Facebook. We normally chat without a problem. However, recently my messages are only sent, not received. I don't know if that contact has actually received them or not. That person still be active on Facebook. I still can see the received icon when messaging other contacts.I also have thought about that that person blocks my message (not my entire account since I still can visit their page). However if that's the case, then I shouldn't be able to send anymore message. So what is the reason of this?
What's the reason for not recieved message on Messenger?
