For whatever reason, since Sunday, I've not been able to receive messages from my sister's phone which is a Note 10 Plus. I was able to see when the message was delivered and read. All of a sudden, I'm not receiving her messages, but she can receive mine. I've updated the app, powered my phone off, and cleared the cache in the app.. still nothing. I don't understand what transpired in a 24 hour period but I don't like it!
