The battery icon in the upper right for my Action 2 with battery module disappeared today.  Tapping up there, trying to drag, longhold, nothing is showing me my battery %.  Both when connected to the (charged) battery module or when just camera alone.  Reconnecting to the battery module does tell me the Power Module is charged 100%.
How do I get my battery icon & ability to see both battery levels back?

Well, it's back today. Weird.
