Facing an issue with my webapp wherein the screen is freezing up on safari/chrome and edge if a user is switching to another app or keeping the phone idle. Browser works fine on other web pages. Its just that page has to be reloaded where my webapp is open. Doesn't happen in desktop browser or any android mobile device. My users are facing it, when I use the same Os version and device, it doesn't seem to happen. Also, not restricted to one screen. please suggest what this issue could be or how to reproduce... it has only started since a few months ago, since last iOs release I believe and now more users are facing it...
