Created attachment 411438 [details] Same PWA on iOS 12.2 (left) and on iOS 13.3 (right) in dark mode after clicking on an Apple Maps link. Look at the back button in the URL bar Reported from some users of twitter.com and first noted in @firt's writeup, https://medium.com/@firt/iphone-11-ipados-and-ios-13-for-pwas-and-web-development-5d5d9071cc49 When using an installed PWA, the In-App browser when you link to external scopes has a bug, where the back button to your PWA shows “◀Untitled” and not the actual PWA’s name or short name (see image below)

Thanks for filing, I believe the issue is occurring outside of WebKit. Apple internal see rdar://54220296.
