Lots of app crashes

I love the app and am using it as my main source for routing on a two month bike tour through Europe. I’m experiencing a lot of crashes on iOS on an iPhone 15 pro. I can’t figure out any consistent way to reproduce the crashes but they happen all the time. Often when I first open the app or when I load a saved route. I just repeatedly retry what ever I was doing (open the app, load a route, etc) and eventually it works after several attempts. 

I have a couple downloaded map tiles and a lot of saved routes (only a couple saved for offline use) and I’ve been frequently using the send to garmin connect feature. Not sure if any of these things would contribute to the problem. 

Thanks!
