JoinOnce does not work properly.
In iPad 9 + iPadOS 16.1.1, turning our app to Sleep with JoinOnce = false does not disconnect the Wi-Fi.
But on the iPad mini 6 + iPadOS 16.1.1, setting JoinOnce = false and turning our app to Sleep would disconnect the Wi-Fi.
Maybe I'm using the NEHotspot Configuration Manager incorrectly?
Well folks, is my code correct?
We develop with Xamarin.
