The Share menu in iOS 13 got a redesign, and the Stack Exchange iOS app is no longer compatible with it. I can still use it to copy the link, but when I try close the menu, it remains stuck.
Opening another app and then returning automatically dismisses the menu, but then I can't use the back button anymore to return to the question list. (I'm still able to refresh the page, so it's a navigation issue.)
Ironically, I discovered this bug while trying to mark this bug report about the iOS app as a duplicate; in the app, the quickest way to do that is to use the Share menu to copy the link to the original question to the clipboard...
