Disabling ANT Communication on Third-Party Fitness Applications
If you use a fitness device that uploads data to Garmin Express through a USB ANT stick, you will need to make sure that all other fitness applications which you use have ANT communication disabled. Your USB ANT stick can only communicate with one application at a time, so if you have another third-party fitness application running, that may be interfering with the USB ANT sick's communication with Garmin Express.
To disable ANT communication on your other third-party applications, you may only need to close the application and ensure that it is not running in the background on your computer.
