Garmin 235 heart rate monitor not working since update of software 4.7

I did an update this morning of my forerunner 235 and now it is not recording heart rate at all. The green light is not flashing and no reading on the watch. I have tried restarting the watch, disconnecting and then reconnecting to bluetooth on phone and disabling and enabling heart rate from app, tried to disable and enable heart rate from function directly on watch and no luck. Not sure where to go to next.
