Troubleshoot sync issues.
Fix problems with rides syncing from Garmin or Wahoo: rides that don't arrive, history that didn't import, duplicates and missing data.
Most sync issues come down to one of four buckets: a ride that hasn't reached Garmin Connect or Wahoo's cloud yet, a connection that has stopped working, a duplicate from two sources, or missing sensor data from the recording.
Quick check first, then walk through each issue.
- 01Ensure you're connected to the internet.
- 02Check that Garmin or Wahoo still says 'Connected' in Settings → Connections.
- 03Try force closing and reopening the WattsUp app.
- 04Wait a few minutes. Syncing can take time after completing an activity.
Garmin activities
Garmin rides sync automatically once your account is connected. Three things are specific to Garmin.
— Garmin Connect comes first
WattsUp receives each ride from Garmin Connect, not straight from your device. If a ride isn't in the Garmin Connect app yet, sync your device there first. It usually reaches WattsUp a few minutes later.
— Connected before ride sync?
Connections made before automatic ride sync only let WattsUp send workouts. If the Garmin Connect™ page in Settings → Connections shows 'Reconnect to enable ride sync', tap 'Reconnect Garmin' and allow activity access.
— Past rides missing
Garmin only shares your ride history if 'Historical Data' is on for WattsUp, and it's off by default. When it's off, the Garmin Connect™ page in Settings → Connections shows 'Past rides need Historical Data': tap 'Reconnect Garmin' and turn it on. If your past rides still don't arrive, disconnect Garmin, connect again and turn it on. Rides older than the import covers can be added as FIT files.
Common sync issues
"Rides not syncing"
The ride hasn't reached Garmin Connect or Wahoo's cloud yet, or WattsUp's access to your account has stopped working.
Make sure your device has synced the ride to Garmin Connect or the Wahoo app first. Then open Settings → Connections, tap Garmin Connect™ or Wahoo, and check that it says 'Connected'. 'Received from Garmin' or 'Received from Wahoo' lists the latest rides that arrived. If a ride is still missing after 30 minutes, upload its .fit file.
"Old rides synced but not new ones"
WattsUp's access to your Garmin or Wahoo account has stopped working, for example because it was removed in your account settings.
Go to Settings → Connections, open Garmin Connect™ or Wahoo and tap 'Disconnect'. Then connect again and allow access. Leave 'Delete previously synced rides' off to keep your history.
"'Couldn't import your history' after connecting"
WattsUp couldn't reach Garmin or Wahoo to import your past rides, usually because of a network drop or a permission that wasn't granted.
Check your internet connection and tap 'Retry' on the banner. If you connected Garmin with 'Historical Data' off, see 'Past rides missing' above.
"Duplicate activities appearing"
The same ride was uploaded as a .fit file and also synced from Garmin or Wahoo.
Rides that arrive from both Garmin and Wahoo are merged into one, but a FIT upload is always added separately. Tap the extra copy on the Train tab or in the calendar, choose 'View Details', tap the delete icon at the top and confirm with 'Delete'.
"Missing power data or heart rate"
Sensors weren't properly connected or the data wasn't recorded on the device.
Check the original activity in Garmin Connect or the Wahoo app has the data recorded. Some data fields may not be recorded by all devices. Ensure sensors were properly connected during the ride.
