Hey @nebregman,
We have been seeing some issues with the ANT+ after updating to Android 10 and we were able to reproduce the issue in-house.
The development team is aware of this, and are looking into a solution. Sadly, we don’t have a workaround at the moment, so if you are able to pair with Bluetooth, that would be your best option.
If your sensors are ANT+ only, then pairing via the desktop app and an ANT+ stick would work, as would pairing with a different, non-updated Android device.
We’re really sorry for the inconvenience and we hope to roll out a solution shortly 
.
