When navigating yesterday I noticed this message at the top of the route summary box. I was getting LTE. I double button rebooted with no effect. I finally went to the navigate settings button. "Online Routing" was turned off. I turned it on and message went away. I don't remember if I previously had online routing turned on but I surely didn't turn it off. The prior time I used nav I didn't get the message. I'm on 12.1.2. Did the function of online routing change un-noticed?
