Hammer GPS fails to provide "Truck Safe Route"

I have been using Hammer GPS for some time and it has been mostly useful. It has had some odd quirks (It will refuse to route through Penfield, NY unless you put a stop in the middle of the village, for example.) But it is mostly helpful.

I have been using it on an old Samsung Galaxy S5 with the maps I need downloaded to the device. The phone had no data and only updated on wifi when I got home. It worked very well but it died a couple weeks ago and I replaced it with a Moto G7.

Oddly, I now cannot get any truck routing unless I am on wifi when I calculate the route. If I try to calculate a route when I am in the truck (without data) it warns me that it is "unable to calculate a truck route because (blank)" and it will provide a car route. (It does not give a reason - the area after because is just blank.)

I have reinstalled the app and redownloaded the maps. I have created saved routes for the areas and runs while on wifi (hoping that would give it the data it was lacking). I can see restrictions on the map data as I navigate, but I am not getting that calculated for my routing.

Did something dramatically change in how Hammer works? Do I really nave to have data to generate routing now (I didn't three weeks ago)?

Any assistance gratefully accepted. Let me know if you need more details.

 

I checked the data settings, and it has permission to use data.

But I don't have data on the phone. Not even a SIM card. It only gets data when I get home and it latches onto my wifi.

 

Sitting here at my desk I can set up a route and it will work perfectly because it is on wifi. Turn off the wifi and it just can't generate a "truck safe" route for the same route.
