Hi Guys,

My Xamarin.Forms App is crashing in production with the following error reported on insights. I have no idea where to start or what this means. Can anyone shed some light on this please?

Thanks alot :)

    I think it is nearly impossible to find out what is going wrong with this information.
    Your best bet would probably be to upload the matching dSYM file to Insights to find out more.

    You can do this by going to your app, select the Settings screen in the top bar and then the DSYMS tab.

    Hi Gerald,

    Thanks for your reply. I believe I had uploaded the DSYMS file, but that is the error I'm getting.

    I got the same crash and on Insights I was able to see that the users got an .NET exception just before and so I think the crash occurs because of that (ArgumentOutOfRangeException). It's certainly specific to my app but look at the other errors reports to see if you can correlate too.
