Apple Watch not tracking activity and heart rate.
After WatchOS 7 update my Apple Watch Series 5 stopped tracking my activity and heart rate.
When I go in the Activity app on my Apple Watch it just shows me a black screen, with time on top of the screen. When I go to the Fitness app on my iPhone it doesn't show my activity. When I go into the Health app on my iPhone it doesn't show my recent and average heart rate, same on my Apple Watch.
Can someone help me?
Apple Watch Series 5, watchOS 7
