If you’re experiencing issues receiving data from or sending data to a partner app, perform the following steps:

1. Make sure you wait at least 15 minutes after adding your data. There can sometimes be a delay in the data synchronization.
2. If you’re having issues sending data to a partner app, check your Withings web dashboard to make sure that the data has been properly synced with our servers.
   If not, make sure your mobile device can access the internet.
3. If you're having issues receiving data from a partner app, check the web interface of the partner app to make sure that the data has been properly synced with the servers of the app.
   If not, make sure your mobile device can access the internet.
4. Try unlinking and then linking the partner app again.

Important note: We improved our API by integrating a new authentification protocol. If you notice synchronization issues between the Withings App and a partner app, please contact the partner app and ask them to update their authentification protocol.
