Nike Run Club not displaying BPM heart rate

I have a new Apple watch 6. The heart rate is not displaying in the Nike Run Club app during running. Checked all the settings based on other recommendations like turn off power save mode, wear the watch one inch above wrist, allow background refresh, etc, etc. Still not working. In addition, the watch face is supposed to show the heart rate, yet it just shows a heart logo with no BPM until you tap the icon. The Apple workout app does show the heart rate. Anyone else have the same issue?
