NRC app on Apple Watch suddenly not working
The Nike Run Club app on my Apple Watch 3 suddenly stop working last week. The complication disappeared. When I scroll down the list of apps on the watch, NRC no longer listed. But from my iPhone XR, under the Apple Watch app, I see that Nike Run Club is listed (see screen shot). But when I go into it, it shows NRC is INSTALLED, but I can not slide the button to "Show App on Apple Watch".
I have tried
1)delete NRC from my iPhone,
2)reset Apple Watch with "Erase Apple Watch Content and Setting".
3)reboot both devices.
4) re-download NRC on the phone.
5) NRC app on phone still not connecting to Apple watch (under settings/device). But Bluetooth shows it is connected to the watch.
6) Apple watch still showing the and behaving teh same manner :(
Help anyone ??
