Running ZML 2.1 on a Moto G/Android 7.0:
In addition to the audible message notifications indicated below, two other points:
intermittently, the map screen quits showing cadence or HR (power still shown, but the cadence line disappears and HR reads something like “6” (computer screen shows correct values, so not a dropout issue))
NO TURN BUTTONS. After a group ride this AM, I carried on for a cool down, but when the turn indication appear on the computer screen: nothing on ZML (either the dashboard or the map page, both of which were functioning normally as best as I could tell), on the map page with the wee little buttons for “toast”, “elbow flick”, etc (all of which are long deprecated?): even swiped to the left with no joy.
