This issue should now be resolved (ver 1.0.24168).
We're currently investigating an issue where Garmin ANT+ speed sensors don't show up on the pairing screen when trying to bridge the signal via the 4iiii Viiiiva heart rate monitor. We will update this post as we have more information.
While there isn't a direct workaround, there may be other options depending on what other platforms and sensors you have.
- If you're on iOS or Apple TV, you can either use a different ANT+ bridge, a Mac/PC with a USB ANT+ dongle, or a different sensor that transmits via Bluetooth.
- If you're on a Mac or PC, you can use a USB ANT+ dongle to receive the signal instead. You could also use a different sensors that transmits via Bluetooth.
