I have been using Garmin Connect with my vivioactive HR since early April. On the Personal Records page I have been tracking my progress with Steps,
etc. I recently joined Challenges. One of the other participants had set his profile as Public. I clicked on a badge in his page that I didn't recognize to see what it was.
His statistics went into my Personal Records page.
They were from a date range that preceded my first use of the device.
I could still see my actual numbers paging back through individual pages, just not on the https://connect.garmin.com/modern/trophy-case screen.
At the end of the challenge Longest Goal Streak corrected itself after a sync with my device but the other statistics did not.
It would seem that there is some transaction that is not thread safe/thread secure. To test this theory I waited to the end of the challenge and tried the same thing on another public profile in the new challenge. The same thing happened.
I have uninstalled and reinstalled Garmin Express just to see if that helped. That corrected my Current Goal Streak, again after a sync with my device but Longest Streak Goal was not (odd since it is a lower number than Longest Streak). Most Steps in a Day, Most Steps in a Week, and Most Steps in a Month also did not get corrected. I haven't figured out another way to edit/initialize those fields.
I've opted out of Challenges to prevent this in the future.
