Was hoping to remotely control Macbook Pro with iPhone XR.
Was messing around with Switch Control settings on the iPhone XR,
hoping to it intuitively.
The iPhone XR has gone berserk:
blue boxes appearing all over screen;
other controls appearing and disappearing;
screen is unresponsive;
asked Siri to turn off Switch Control - he says he can’t do it.
researched elsewhere, one solution was to press Home button 3 times; iPhone XR has no Home button.
Appreciate any input.
