Why doesn't mapmyrun load up seamlessly like before?

The problem is that when I started my last couple of hikes, the app wanted me to sign in with my email and password. I was starting a hike, and it was awkward to do. I couldn't stop our little group. I tried a couple of times, but it wouldn't let me in. I can't be messing with signing in on every hike. It never did that in the past. Too bad. I used to love the app.
