Good morning!
I wanted to start my first app, but I'm running into some issues pretty quickly!
I went to the appstudio.arcgis.com and started with a Map Viewer template. I added the images and added the in for in both the App Info and Map View Settings tabs and used a public web map. When I saved and finished, I clicked on customize app and I had already downloaded AppStudio for desktop, so I launched (Step 2: Open the source code of your app in AppStudio). When I click Run, I get 4 AppRun Errors:

When I go to edit MapViewerApp.qml Line 26 (I'm just assuming this is where to go to find the errors?):
import Esri.ArcGISRuntime 100.2
MapPage.qml Line 210:
parent.checked = true
ScreenShotsView.qml Line 1715 - there isn't this line, it stops at 427
I've also tried to open this in AppPlayer on my phone. I can download it, and it brings up the initial screen. When I click start though, it just has the waiting circle, even after 5 minutes.
I'm not sure what step I missed, or what I can do to get this working.
No clue what the ArcGIS.AppFramework.InterAppCommunication module is or how to install it? Is this the cause of the problem? Would that also be why I can't use the app on my phone in the AppPlayer?
Thank you for any help!
