App frequently crashes, when using it sometimes it doesn't give notifications. Frequently it says I am deviating from route while I am not

Could not start the app the permissions it wants are unacceptable and way beyond what is need. I really can not see any reason the app needs access to my files or to make a phone call. They basically want free run of all my personal data there is no good reason for that, i can think of several bad reasons though. Because it is a waste of space unless I give it access to my personal data which is not required to see the maps I un-installed it.

Need call access to manage maps? Does the app need to call an operator in the background to get from point a to point b? Crashes often and is unreliable. After reinstalling, I found that I could deny permissions by following the prompts. But I can use this app for nothing but prompt for permissions. Reinstall and grant all permissions including notifications. Then it looked like app was going well. So often crashed may due to i disable call permission in phone settings before.
