During a course ride I could not return to the data screen or the standard map view. Only options were the course with STOP as an option and an unfamiliar map view.

Why did my Edge Explore not allow me to find either the Data Screen or my configured map screen or the widgets or the Home screen but only offer me either the course outline with an option to STOP (in blue) or a zoomed out map that was completely unfamiliar to me? Did I touch something? is it a bug. All the turn warnings continued to work and when I got home, and saved the ride, it seemed back to normal. Really frustrating and distracting and a bit dangerous to lose your rag with tech mid ride.
