I have a user that is getting the following exception in my Dog Tracker app on the VAHR. I then played with my wife's VAHR and got the same thing. Although after playing with it a bit, the error went away and things are working properly. After this, I did a rebuild / upload of the app to the store in hopes that some combination of the new tools were the cause as it was in January I last updated the app. The user now seems to have gotten his working but that could just be coincidence like for me. Both of us were on fw 4.4, the latest.
The app opens up an Ant Channel for the tracker profile communicating with a Garmin Alpha. I haven't heard of any issues with any other devices and have never had the issue on my 935 despite using it multiple times a day.
I'm guessing the "native function" in the stack trace puts it outside my control. The "Unable to Acquire ANT Channel" also must be coming from the firmware as I don't have that message in any of my code.
