Anyone use it. Been using it for over a year. It’s extremely slow, glitchy, crashes often and becomes unusable after saving more than 10 or so waypoints. Tonight I paid an additional $30 to be able to put a second copy of havasu on an additional card. Now the app just crashes every time I hit transfer. Anyone else have these issues. It’s handy but it doesn’t work well at all. Not sure why they don’t update the app and make it work correctly.
