6. I can’t have both an android and iPhone connected at the same time, because I won’t be able to use Android Auto, I’m forced into Car Play

Just got a new work truck, a Ford, with android auto and car play. This morning was the first time I plugged an iPhone and android in at the same time. I had plugged in the android first and a quick look I wasn’t able to switch to the iPhone without unplugging the android. I never plugged the android back in so idk if it prefers one over the other or just whatever is plugged in first. Could that be the same issue?
