Have used Fenix3 and now Fenix5 for running for several years, but just started trying to use for pool swimming. No matter what settings I try I can't get the POOL SWIM activity to automatically record intervals. I have the activity pool length set to 25 meters, swim stroke detection on, and an alert set for 2 lengths, but every swim shows up as a single interval. I understand that I could stop after every two lengths and press the lap button twice, but my hope was that I could do a continuous swim, changing strokes every two lengths and have the device automatically record each two lengths as an interval with its own statistics. That way I could compare my stroke performance. Is this impossible or am I doing something wrong?
