I'm having the same problem. Was working great until two days ago when we had a rain storm. During the storm, problems, but now that the storm has cleared, Waze still can't get a fix. Google Maps and other apps are doing just fine.
This happened to me before in storms, cut after a few minutes, it would finally get a read and work properly. This time, no dice.
I am having this problem as well. and it also happened shortly after some storms. but that was two weeks ago. still not working while google maps spot on. I miss my waze. also i don't see as many other wazers out there like i used to. and the ubiquitous stop light cameras here in Chicago are all gone as well. Help!
