Virb Ultra compass data + app connectivity

So I've tried asking Garmin support via email, and have been getting responses that don't even relate to the question I am asking. The question is, why is the Ultra 30 recording what seems like interpolated compass image heading when using interval mode photo. Surely having a 100hz compass sensor should mean it's capable of using it?

To make this is more on-topic, the app would randomly fail to connect to the virb, and the remote wake never worked
