Hello- after I reluctantly migrated my account from Fitbit to Google, my historical heart rate zone data was lost. Previously, my peak zone began at 140 bpm. After migration, that was changed by Google to 108. All prior data was also "corrected" to this new zone. This is outrageous. Moderator: yes, I am in the correct Google account. And yes, I understand that I can create "custom zones". Unfortunately, I don't remember the bpm boundaries for any of the other zones. I merely want the correct historical data, and this issue is on Google to address.
