OBDEleven vs OBDEleven Vag

I’m new to OBDeleven. I own a Volkswagen ID4. I first tried the OBDEleven app; it would get stuck on ‘detecting vehicle’ and ask me to ‘turn ignition on’, there is no ‘ignition’, I just press the brake to turn the car on. If I use OBDEleven VAG it works but every time it suggests to switch to the other app (without VAG). Is this normal? Is the OBD supposed to work with the ‘OBDEleven’ (without VAG) app?
