There are a few reasons your Fitbit data may not be updating in the application.
The first place to check is your Fitbit application. Make sure to sync your smart watch with the Fitbit application by refreshing the page (dragging the screen down to update). If after syncing, your Fitbit data is still not displaying in the Fitbit application, the problem needs to be taken up with Fitbit Support. You can search Fitbit’s help center to see if you can find the solution: help.fitbit.com/cwsupport or contact them by email: cwsupport@fitbit.com or phone 844-534-8248. If Sensable Health provided your smart watch, let them know your device came with the Sensable Health program which will verify its purchase and one-year warranty.
If your data is appearing in the Fitbit application, the issue lies in transmitting that data to Sensable Health. Navigate in the Sensable Health application to the “Connected Devices” tab within your “Profile”. Make sure that under “Connected Devices” a Fitbit Watch is shown (not an Apple Watch). If Apple Watch is appearing, select the button to switch devices to your Fitbit Smart Watch.
If the connected device was correctly listed as your Fitbit smart watch, the two most common reasons are 1.) The incorrect Fitbit account is connected to the Sensable Health Application 2.) Fitbit permissions were not allowed during the initial setup. In either case, the solution is the same. Navigate in the Sensable Health application to the “Connected Devices” tab within your “Profile”. Disconnect your Fitbit account by clicking the “Disconnect” button. You will be allowed to reconnect to your Fitbit account. Be sure to sign into the same account your devices are connected with and to allow all requested account permissions.
