I use the Stryd running power data field and sometime last July it just stopped showing up in Garmin Connect. On July 10 it was there when I uploaded an activity:

But, when I ran again on July 13 it was missing in the uploaded file (well, at least the presentation on GC):

Apparently neither it nor any other Connect IQ data field has shown up for me on Garmin Connect since then! The data fields, though, work fine on the watch. I can see power just fine. And, the data shows up in Training Peaks and if I look at the fit file using Golden Cheetah.
In an effort to debug this problem, today I went out on a run with my Fenix 5 and my older 920XT, both with the latest firmware installed and both running the same Stryd Running power data field and the Moxy 1st sensor data field. While running, data from both my Stryd and my Moxy showed up on both watches just fine, but when I uploaded them to GC only 920XT shows the Connect IQ data fields:
Fenix 5: https://connect.garmin.com/modern/activity/2478375543
920XT: https://connect.garmin.com/modern/activity/2478363738
At this point, I'm at a complete loss with how to get the Connect IQ data fields to show up when I upload from my fenix 5. I've tried resetting the fenix 5 to factory defaults and that changes nothing. Any suggestions on how to fix this would be greatly appreciated.
