No Running Power data field with Fenix 7 and Garmin HRM Pro+

The native Running Power will be available with the next firmware update. Until then, you have to install the IQ app onto the watch AND add it to one of the data pages in the running apps on the watch.
That combination works.

Sitronen, thanks, but I've already added that IQ app. 

After that, I'm not able to add either a Power screen or a Power datafield

Power Screen Attempt

1. Hold MENU.
2. Select Activities & Apps
3. Select Run
4. Select Run Settings
5. Select Data Screens
6. Select a data screen to customize
7. Scroll through screens until ADD NEW
8. Select ADD NEW

But then there is no Power screen option to add.

Power Datafield Attempt

Do 1-6 above and then:

7. Select any existing screen
8. Select Layout
9. Select Data Fields
10. Select a field on the screen to change
11. Scroll through the available Fields.

But then there is no Power data field.

Were you able to get Running Power to work with one of these procedures, or by a different one?

I think native running power is coming with the next public release. It’s definitely in the beta software, just not available in 8.37 I believe. 

I can confirm that with FW 9.31 on the watch and FW 8.8 on thee HRM Pro you get running power in GC and GCM.
