Apple Maps Won't Navigate (Sporadic Problem)

Has anyone else ever had this problem? It seems to happen randomly. I do on-site repair work, always going to a different location. So I use my navigation almost daily. I just use regular old Apple Maps. Sometimes I type in an address, sometimes I tell siri. Occasionally I send the maps over from my home computer (which may be one of the triggers of this, I'll need to do more testing). So normally you pick your address, you hit "GO" and you're off with maps and verbal turn-by-turn directions. When this no-navigating problem happens, you hit GO, and you get a map, but it's as if you haven't actually picked your router. Yet somehow you get sort of an overview summary of the 'steps' of your directions, but it doesn't read them to you, or indicate turns coming up. Yet it knows exactly where you are. You can have your waypoint drive right down the route tracking you, and theres a blue route line, but they aren't "linked". It's extremely annoying. There doesn't seem to be a way to KICK it into navigating. The day I took the screen shot below, I was repeatedly cancelling navigation, and reinitializing my route, but it kept getting stuck and not giving me directions. Does anyone else ever have this problem on their iPhone? My phone is an iPhone 8 running the newest iOS. I've had this problem in the past on my 6S too.
