App controls don't work

Question

I installed an Evo One with a Mazda C5 harness. In addition i installed the Evo Start LTE module.
The remote start using the remote control works perfectly, but no controls work when i try to send them from the app.
I am able to see the car location, so the GPS reports correctly and the state of the car changes correctly in the app when i use my remote control (i.e. opening and closing the door). But if i try to open/close the doors using the app, or try to start the car, the app states that the command executed successfully, but nothing happens on the car end.
In addition, the fuel state is shown at 0%, while battery charge does show.

Any help resolving this issue is appreciated, TIA.
