A new version of the Garmin Connect app has been released that fixes this issue. Users no longer need to use the workarounds listed below. You can now re-enable syncing with Apple Health Kit or change your iPhone's time zone setting back to the correct location/Set Automatically.
Previous Workarounds prior to release of 4.12.1.2:
Workaround #1
Disable Apple HeathKit:
- Open Health App
- Go to Sources tab
- Touch Connect
- Touch ‘Turn All Categories Off’
This will prevent data from being synced to Apple HealthKit from the Garmin Connect App but will prevent the app from crashing until the fix can be implemented.
Workaround #2
Change iPhone’s time zone setting to Reykjavik, Iceland (or other country that does not participate in Daylight Saving Time):
- Touch the Settings App
- Touch General
- Touch Date & Time
- Turn off Set Automatically
- Touch Time Zone
- Search Reykajavik, Iceland
This workaround will allow you to sync your data to the Garmin Connect App and Apple HealthKit. Your device will potentially be in a different time zone depending on your location. Once the fix is released you will need to go back into your iPhone’s setting to update the time zone once more.
