Hey @aivarouskaya,
Thanks for your post. We're going to send this order to our Support team so they can take a look at your account and try to figure out what's going on. If you have a similar question please submit a support ticket and we will investigate further.

From our Support Team:
Please try following the steps below to see if one of them resolves the issue.....

1. Ensure the device can first broadcast as a Bluetooth heart rate monitor; if it cannot broadcast as a monitor, we would not be able to detect it under the new settings. Some devices may have a broadcast mode you need to turn on or enable from within its own settings.
    


2. Ensure that the Bluetooth monitor is not connected to other services like Garmin Connect or Wahoo Fitness. You may need to enter the app settings of the other services to unpair the Bluetooth device so it can be paired to the Strava mobile application*. Bluetooth monitors normally may only connect to a single service on your device at a time.
   
   *If your device is still detected or being picked up in another service while you're trying to pair to the Strava mobile application, the Bluetooth monitor has not yet been properly disconnected from the other services. 
    


3. If you're still experiencing issues, please try "unpairing" the Bluetooth monitor from your mobile device completely by following the instructions for your device below:
   -Android
   -iPhone


4. Once unpaired, please try pairing the Bluetooth monitor to your phone again and connecting it within the Strava mobile application. You will want to ensure the Strava mobile application is on the latest version (above version 200).

You can learn more about pairing a Bluetooth device on our support page here:

If you're still experiencing issues after trying the steps above, please submit a support ticket and include the name of the Bluetooth monitor so we can investigate its compatibility. Also include a screenshot of what may be happening or screen recorded session when you try to connect in your email so that we can further investigate.
