It sounds like you're aware of what a routing app is, but just to confirm details: A routing app provides navigational directions between two locations. It is enabled inside of an Xcode project by going to the Capabilities tab, and adding the Maps capability, which will then show you a list of checkboxes for the transportation modes by which you're able to provide navigational directions between points. Those checkboxes correspond to values added to your Info.plist file under a key named MKDirectionsApplicationSupportedModes. It sounds like you're not providing directions, but you should check to make sure the above capability isn't enabled accidentally. And if you're not providing directions, also don't enable this capability just to try and solve this error, as I've seen people get tangled up further by trying that. If all of that looks good and that capability wasn't accidentally enabled, then the next thing you should do is to open a bug report with the details of your App ID and the build number
