Same here. Got a 520 Edge and 4iiii Powermeter for outdoors and Tacx Flux for indoors.
FTP and VO2 max are perfectly shown on the 520 but can't seem to find it's way to the Garmin Connect app.
(VO2 max is shown in Garmin Connect app, FTP isn't..)
Starting to get annoying, especially because you do see the info per ride in Garmin Connect, so why won't it transfer to the actual overall FTP page.
I've sent an extended mail to Garmin about a week a go or so, no respons so far........
Extremely surprised about the amount of people having this issue for over 2(!) years already and the lack of respons from Garmin (hello?!)
"certain conditions / configurations"
Well that's one of the most frustrating responses ever. What are the conditions!? If we knew we could understand the problem or perhaps there's a setting to change or a type of workout we need to do. As it is you've given us nothing except to confirm that you have a problem. Apparently it's a problem you don't intend to fix as I'm still getting this problem 3 years after the thread was started.
