Latest firmware
For me as well
I have noticed this today as well with v14.13
Not only the empty power graph, but also the incorrect zones performed after the exercise, and does not update ftp or lactate threshold. 14.13
I did a run yesterday with a HRM-Tri and it looks okay (14.13 f/w). I have an long-standing issue with the power zones not being populated for Zwift rides.
Same here on FW 14.13 and with HRM-Pro
Same here! Ok on Garmin Connect but KO on watch...
I think it still miscalculates the times in the performance zones, where it shows me 0% in red zone. This problem has been around for a long time.
