I use the Yelp app to look for places to go for food and such, and once I find somewhere that's worth going, I press "Find Directions" to open Waze to go there.
So for example, I search for "Del Taco," go inside the Yelp page for its nearest location, and press "Find Direction." This opens the Waze app, and then the Waze app I guess just stops loading after opening, which gives me the blue screen.
I've tried zooming in/out, everything. It's not an ocean, just maps that fail to load. I have to turn off Waze, open Waze manually (not via Yelp) to get it to load the maps again.
Anyone who's using Android Yelp + Waze should try this and report back to see if they're experiencing the same problem.
