You can’t have it both ways. Apple either miscommunicated this ever since Control center was added till today or they are miscommunication pang today.
I would lean in the direction of miscommunicating today because Apple has spent years teaching its customers that this behavior means X and now it’s been changed to Y.
And that's the expected outcome of me turning off wifi. Something I deliberately tried to do through clicking the on/off toggle.
I agree with parent poster: Either apple has been miscommunication the whole time, or they are miscommunication now. You can't have it both ways.
