I have set up the Connected app as described in the challenge and I am able to log in to Salesforce via the iOS simulation and see my log in via the app under the Connected Oauth usage info page for the app. However, I still received this annoying error message: 'The 'Trailhead_Native_iOS' Connected App has not been setup'. Can anybody help?

Thanks

I am trying to complete a this simple trailhead challenge on Customizing Compact Layouts
https://developer.salesforce.com/trailhead/force_com_admin_beginner/salesforce1_mobile_app/salesforce1_mobile_app_compact_layouts
but I am getting this error:

Challenge Not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: UPQCQUMM

I can see the Compact layout correctly in Salesforce 1. Could you please help, would like to complete this trail :)

Thanks!
