Workout: Time Goal

When I set 'time' as a goal in a workout (any type or 'other') the 'time goal' ring during the workout never progresses. If I set the time goal at 10mins, although the workout app captures my data, (calories, distance, heart rate and actual time or whatever) the 'goal complete' always registers at 2%, never the actual time I exercised. Also I don't get notifications such as halfway progress or goal complete. I see other people have reported this problem, but don't see any resolution.
