Hi there - Since the last iPad ARC Pro software, I can no longer calibrate a car, any car. When I enter the calibrate function, the "NEXT STEP" at the bottom of the display does not show up. I can say that the iPhone version with the same software version works perfectly well. The software in use on both devices is: IOS 13.2.3 On the iPhone, the Scalextric Application settings read: App version v2.4 B19Model Scalextric ARC PROFirmware 2.6Hardware 1.0.1PIC 7.3Base 0.13ControllersOn the iPad the Application settings read: App version v2.4 B19Model Scalextric ARC PROFirmware 2.6Hardware 1.0.1PIC 7.3Base 0.13Controllers 1=0.13I think this is a truly great product that I enjoyed for several months, until the latest iPad software update, that is. Thanks in advance for your prompt reply. I really appreciate it.
