App just stops working at times – Map My Walk by Under Armour Review

This app was ok for a bit, paid the premium and avoid the ads. But sometimes, more often these days, when I go to record a walk, the app just goes to a blank white screen. It’s happened a few times now. I’m asking for a refund on my membership. I’m pretty sure I won’t get it. Support is non responsive.
