iGlide loses saved routes

I’ve need flying with iGlide on an iPad mini 4 for a couple years now. It’s really good, but it has an annoying feature of losing all of the saved routes every couple of months. I usually happens right after I’ve entered a long route. It’s frustrating. I enter a new round with 6 turn points and then I hold my breath. Is it going to lose them all or not? And when it looses the route I’ve just entered it also looses every other route that I’ve entered over the past couple of months. Is there a way to recover the saved routes?

iGlide does not lose custom turn points. It does not lose my flight logs. But it loses saved routes. Has anybody else seen this? Is there a fix?
