Radar HD (NOAA) – Radar HD - Future NOAA Doppler Weather Radar Review

I loved this app until the recent update. Now I don't understand how to use it. Where it shows the radar in real time, going back an hour or so extending to present time, it extends past present time by an hour or so, whether I select "past", "present" or "future". I don't understand the plus-minus going up to 3+ or 4+. I keep trying to use it because I loved it, but I need instructions - and that's just not right. DotNorth
