Problem setting the AV output to "on"

There appears to be a bug in the app where it does not allow the user to switch the AV button to "on". Without this ability, the display attachment shows nothing but a blank blue screen. Tried this on 2 different Yi cameras with the same result. Did not happen on the earlier app. I hope this issue is addressed in an update soon.
