First, from tab 1, I open a page with NavController and push.
Then I go to tab 2 and, on returning to tab 1, the page on which I clicked is still open. I want when I change Tab to close those pages, can anyone help me?
I think this breaks the UX contract of tabs. Tabs are meant to be little "sub-app"s that are independent of one another, so actions taken inside one of them should not alter the navigation state of another.
