problemas pulso en aplicación

Hey ​@Pijo,

What device are you using to record your Strava Activity? 

Es una cinta pectoral Garmin hrm

Hey ​@Pijo,

Thank you for providing this screenshot.
Could you please try following the steps below to see if one of them resolves the issue?

1. Please 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. 
    
2. 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
    
3. 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).

Buenas gracias por contestar. He hecho todo lo que me comentas y sigue pasando lo mismo. 

Pobre que se conecta a la aplicación pero no sale el pulso. Le he cambiado la pilas y lo conecto a otros dispositivos o aplicaciones y funciona. Solo me da ese fallo con strava 

Alguna idea más???

Gracias de antemano y espero su contestación
