As I mentioned before, how much is google paying you to default to their useless map? You may say it is faster but it is not when you have to click again to get to where you want to be and it goes back to the useless default map if you view details of a cache then go back to the map. Perhaps it would be better if we had an option in settings where we could choose the map we want and not have to endure the seemingly endless clicks.
I noticed today on the mobile app that if you select "view in browser" it will take you there but if you then select "view larger map" it takes you back to the mobile app, to the map you may not want, and never actually allows you to continue as a "spinning arrow" icon appears and has not stopped for an hour. I exited the app, restarted it and the arrow is still spinning and nothing happens.
Oddly enough, I was checking out an area the other night for a future cache run. One hour or so later I was plagued with ads on facebook about businesses and activities in that same area. Was this a coincidence or is google tracking our every move? What's next? Will we be inundated with ads like youtube? The changes you have made, starting with the elimination of challenge caches, are changing this from an an entertaining activity to just another invasion of our privacy.
