Closed davidbauer2 closed 2 years ago

davidbauer2 commented 2 years ago

Description

We have a user that is unable to open our app. They have uninstalled, re-installed, restarted their phone and updated their phone to iOS 15.1 with no luck getting it to start. We have tried multiple different versions for them as well. They have provided the crash log which is shown below, it is the same each time it crashes for them.

The device they are having an issue on is a iPhone XR running 15.1. They are able to open the app on their iPad and spouses iphone without issues.

Steps to Reproduce

Unfortunately we are not able to get the issue to reproduce on any of our devices or simulator/emulators.

Expected Behavior

App to start up without crashing

Actual Behavior

App crashing on startup.

Without a reproduction or useful logs it's quite impossible to diagnose this. Sorry about that! Let me know if you have a more .NET related stack trace of any other information.
