Array.add() missing from epix simulator

The epix simulator seems to have problems with Toybox.Lang.Array.add() method. The sample code works in other simulators.

To reproduce, clone the repository
https://github.com/samuelmr/garmin-updatecount

Run
monkeyc -f monkey.jungle -d epix -y ~/connectiq/developer_key.der -o UpdateCount.prg connectiq monkeydo UpdateCount.prg epix
Result:
Could not find symbol 'add' Symbol Not Found Error in onUpdate (.../UpdateCount/source/UpdateCountView.mc:28)
