Sorry for my bad english.
I spent about 2 weeks in interaction with support via email. It is a little bit painful;) Very slow replies and misunderstanding of the issue.
So, what's wrong?
When I go to HRV report in GC web interface, I can't see any chart. All other charts work well. Moreover, HRM chart in GC mobile also works well. The only web HRV chart is invisible.
I did a little investigation and found that there is exception in chrome console.
adrum-4.3.2.0.js:20 GET https://connect.garmin.com/modern/proxy/metrics-service/internal/manualstresslevel/daily/70229487/2018-08-24/2018-08-30?_=1535635680190 400 ()
I attached full console log.
Email support suggested me to use another browser. The same result.
I think that something wrong with ajax chart data loading.
Any thoughts how to fix it?
