The “Ok Waze” feature isn’t working quite right – Waze Navigation & Live Traffic Review

The app responds to “Ok, Waze” but doesn’t recognize anything after that. UPDATED: Apparently the feature doesn’t play nice with banner notifications from other apps. If I get a banner notification while I’m driving, and I don’t clear it, that seems to be when the feature stops working. Don’t know of a good workaround yet.
