Instinct Won't Recognize Media Playing and Won't Get Notifications

Hi,

For some reason that I don't understand, my Instinct won't recognize media playing from my phone anymore even though it's connected. It has been like this for a few weeks now. I am currently using the latest update (5.40) but even before I updated, it still didn't work. The watch only says "Start Music on Phone.". So I can't pause and resume videos for example. Also no notifications is received on the watch. Can someone please help me?
