My account seems to be corrupted in some way.
In the list of Reports under https://connect.garmin.com/modern/report#collapseThree there should be Normalized Power, but it is missing, so that the Reports widget and the Report do not show any data for Normalized Power even though I have it in my activities.
I created a new account, paired my device, and uploaded this week's fit files and the reports widget showed the Normalized Power, and Normalized Power appeared in the list of cycling reports, and showed my data.
I tried removing all my devices from Garmin Connect, and then re-adding them with Garmin Express, but it didn't help.
Is there any way to 'refresh' my account?
I am in touch with support but they don't seem to recognise that there is a problem.
