My Garmin HRM pro died after 7 months of usage and it wasn't turning on despite me trying multiple new cr2032 batteries,
while trying to assist with this issue, the Garmin support agent made me reinstall Garmin connect on my phone, and also made me restore
the default settings on my Forerunner 945 LTE.
Since then I've noticed that the historical training load data is incorrect.
Between 23rd Jan to 3rd May it is showing me as Detraining.
But if you look at the activities graph, I have clearly been running in that duration
So the activities still exist, but the training load data was lost.
How can this issue be fixed?
