Troubleshooting Sync Issues

Fix problems with Wahoo activity syncing

Garmin Activities Cannot Auto-Sync

Due to Garmin's Developer API policies, WattsUp is unable to automatically sync activities from Garmin. To get AI coaching feedback on your Garmin rides, you'll need to manually upload your .fit file.

Quick Checks First

Ensure you're connected to the internet
Check that your Wahoo connection is still active in Settings → Integrations
Try force closing and reopening the WattsUp app
Wait a few minutes — syncing can take time after completing an activity

Common Wahoo Sync Issues

Activities not syncing from Wahoo

If your Wahoo workouts aren't appearing:

Ensure your ELEMNT device has synced to Wahoo Cloud first
Check WattsUp has permission to access Wahoo workouts
Go to Settings → Integrations → Wahoo and reconnect if needed
Verify your Wahoo device is connected to WiFi or paired with your phone
Try manually syncing your ELEMNT device

Old activities synced but not new ones

If past activities synced but new ones don't:

Your Wahoo connection may have expired — reconnect in Settings
Check if you need to re-authorize WattsUp's access
Wahoo requires periodic re-authentication for security
Try disconnecting and reconnecting your Wahoo account completely

Duplicate activities appearing

If you see duplicate activities:

You may have uploaded a .fit file for an activity that also synced from Wahoo
Check if the same activity exists from multiple sources
You can delete duplicate activities by swiping left on them
Consider removing redundant uploads

Missing power data or heart rate

If an activity synced but data is missing:

Check the original activity in 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
Try re-syncing the activity (delete it and let it sync again)

How to Manually Refresh Wahoo Sync

Open the WattsUp app
Go to the Calendar tab
Pull down on the screen to refresh
Wait for the sync indicator to complete
Your latest Wahoo activities should appear
