I have a Galaxy Note Edge. I went through steps to upgrade OS to Marshmallow 6.0.1 this weekend, and now Waze is acting up horribly. It kept bleeping at me like it was changing my route for me, but nothing changed at all in my route and it would update me on my next move. I uninstalled it and reinstalled it, and think it might be good to go now. Took a while for it to "prepare voice navigation" and it crashed my phone a couple more times, but it appears now it might be ready to go. Very frustrating. :-
