Welcome @Leo_Groenendijk

So after a short stop, when you run your car again, the speedometer doesn’t work in the app?
Did you force close the app on your iPhone 6? or is it still running?

If I understand correctly, you have to unplug and re-plug the OBD2 connection for it to work again?
I think your issue may be in the app connection not the physical connection.

What car model do you have?
@Julieta do you think this is a technical issue?
