All of a sudden, Waze won't open for me (on W10M 10581) or two other people I know (on WP 8.1), even after reinstalling it.
Same here. Stumbled upon this while searching to see if it was general. Waze opens and closes in less than 2 seconds. Lumia 930 with 8.1 (latest without insider) and also a Lumia 920 with fast insider. Both the same thing. Today was all around Here Drive which I keep updated in maps, settings, favorites, etc. I always had a feeling something like this might happen, lol.
Think it's over or they are actually working on a update for Windows?
