That’s not actually a hard reboot. Hard reboot is disconnecting the 12v battery and unplugging the HV pack under the seat. The brake pedal thing is just something made up by the internet.I wouldn't call for service until I deleted the app from my phone and reinstalled it. I'd also perform a hard reboot of the car by pressing the brake pedal down and both scroll wheels until the screen blacks out. I had a problem with my passenger side windows not working. Soft reboot didn't remedy it. Hard reboot solved the problem.
