This issue is back since I installed v0.0.9-30. Sometimes it does resume a route and sometimes it doesn't. I haven't figured out a pattern yet. When it doesn't resume, no route is shown, no voice prompts are heard and the icon that shows directions isn't visible, but if waze crashes while in this state, the next time it starts it will prompt to resume the route. It may be that I didn't test v0.0.9-29 long enough for the problem to occur.
