How to save page state

Im using ionic 4 beta, I have build a PWA which it’s served on Nginx. Over the browser the PWA works normal but when I save the PWA on my iPhone screen I have a trouble.

I start the PWA app from my iPhone screen, then Im going back to the iPhone main screen from the app and then when im going to return to the app, the app go to the main page instead of the last page I visited.

Thanks in advance.

That is a known issue with PWAs on iOS :frowning:
