Starting with iOS13 there is a new notification that appears "sometimes" when public wi-fi networks are found. See this screenshot for an example (remove white spaces): https:// i.imgur.com/MyuGr45.jpg Since one of our businesses is to manage Captive Portals we would like to know: 1) when this notification appears (since it only appears for certain networks and not always); 2) how can we suggest iOS to show it (e.g. do we need to insert some "magic bit" into access point beacon frames?)
