Return to previous page is invalid

app.views.current.router.back(’/’,{force: true});
I want it to return two pages.
This is not a problem in Google Chrome debugging, but it doesn’t work on Android and ios, just return to the previous page.
This problem has puzzled me for more than a week. I am very urgently resolved. Thank you for this great framework.

Is it a cordova app? Post your full object you have specified in routes and what is in pushStateRoot parameter?
