Question: Mac Immediately Marking All New iMessages as Read
Recently I have encountered an issue where my Mac is sporadically marking all new iMessages immediately as "read" before I even look at them. It does not give a notification, play the sound, or show the red notification number on the application. In addition to this, I have also noticed that when I do read messages on my Mac, it no longer clears the notification on my iPhone 8. What could be the cause of all this? Just for additional information my Mac is running High Sierra 10.13.4 and my iPhone is running iOS 11.3 and I have not changed any iMessage settings that I know of.
MacBook Pro, macOS High Sierra (10.13.4)
