Maps

I'm on ios 10 with an SE. I've used Maps since it's been out. Not the greatest nav app but well integrated. For about 2 months it's been doing the following:

Crashing, at open or in use. I can't remember the last time I've seen any app crash on iOS.

Shows incorrect location for me. 15 miles off today. Hitting the location icon does nothing to correct the problem. Navigation to Contacts showing incorrect location. Contacts that used to be fine are now taking me 10's of miles away from where they actually are.

Taking forever to determine routes. Frequently sits there and simply spins forever.

No alternate routes shown anymore.

Google Maps, which I'm now using, works fine so doesn't appear to be a hardware or iOS issue.

This all started happening about the time iOS 11, and it's new Maps app, was released. Anyone else finding the Maps app is now useless?
