Current Behavior

When I navigate to a page that has a StatusBarBehavior and then back the previous colors are kept even if the page I returned to specifies a behavior with different colors.

Expected Behavior

The colors to change whenever a user navigates.

Steps To Reproduce

Click the Navigate button and then navigate back

I agree with @pikausp. I expect the status bar to change when the page the behavior is attached to becomes visible. So effectively the OnAppearing logic

I would say, the expected behavior is to not change the StatusBar color when we navigate back, it’s not something that should be attached to a Page, but a global configuration. I can’t remember an application that changes it on every navigation. If the dev wants that StatusBar color changes when navigating he should control that. We have static methods that can be called on the NavigateTo/NavigateFrom methods.

@pictos page A has a style, page B has a different style. Would you say it makes sense for the page A to have the style of Page B when returned to?

I could understand if you wanted a property on the behavior to activate this behavior, but I think it’s a reasonable request/expectation.
