Can’t connect to ID4

I just tried using with a brand new OBD Eleven NextGen, but I can’t even get to talk to the car. The dongle is detected by the app, but I keep getting the error ‘turn ignition on, retry?’ I have tried pressing the brake, pressing the steering column button, getting out of the car, lock/unlock, open the hood. Nothing.

I tried both ‘OBDEleven VAG’ app (which suggests you to use ‘OBDEleven’) and ‘OBDEleven’ without ‘VAG’

I’ve read of other people with this exact same problem, but I haven’t found a solution
