I’ve fixed nearly all problems with my app that had been introduced with iOS 10 by applying a new Content Security Policy. But still, one very annoying problem remains: If a user downloads my app from the app store for the very first time and tries to login, nothing happens. The login dialog just stays in the “waiting” state forever.
There’s no clue in the logs (Xcode, Safari) about what is going wrong, the login just silently fails. If click around the app before trying to login, the login sometimes works. It also works if I close the app completely, restart it and try to login then. But not if I try to login right after the app store download. Any ideas on what is happening here? I’m using useraccounts:bootstrap, if that matters.
Thanks for any advice.
