Probably the control relay has failed. Those two lead wires carry the DC current to the motor, the polarity is reversed with opposite switch positions. I doubt the problem is at the motor or the wires leading to it. You could remove the connector at the motor, test each wire to see if you have current when the switch is pressed in one direction and when pressed in the opposite direction: a tester should indicate the polarity as -12V in one and 12V in the other if the everything is working properly. (Connect one probe of the tester to the red wire and the other lead to the white wire. You may be able to do this without removing the connector if your tester has a narrow needle probe and can reach the metal of the connector where the wires go.)
If you don't have power in each direction, then find the control relay board for your awnings and check the relays. I'm assuming you have relays because you mentioned remote and APP controls. The switch, remote, and App all trigger a relay to send power to the awning motor.
