Sorry, it looks like the needed link in the framework to resources was accidentally added to my .gitignore so the uploaded version was missing an essential file (but could be found on my local filesystem). I’ve fixed it and created a virtual machine with a user who has none of my local file structure so I can check whether this is an issue in the future.
The current uploaded version worked fine for my test developer, so I think it should work fine for you. Please re-download and make sure you’ve deleted the previous two downloads to be sure there’s no unintentional interaction or caching before running the sample app with the new version. Thanks for hanging in there.
