Someone who downloaded my app from the app store reported that the app crashed upon opening it. However, upon checking the crash reports for the app in the xcode organizer window, there are no reports of a crash. Could a crash not appear in crash reports for a certain reason?

When I try testing the sign-in with apple button on ANY xcode simulator, it doesn't work. After inputting the password to sign in, the spinner in the password field never stops spinning and nothing from the oauth methods gets printed. I have tested the sign in on multiple real-world devices. It always works. It seems to just be simulators that are causing the issue I'm worried my app will be rejected because of this. Has anyone encountered this? Any fixes?
