From what I gather the correct setup for loading and error susbstates when using pod structure is:
…/app/pods/mypath/template.hbs …/app/pods/mypath/route.js …/app/pods/mypath/loading/template.hbs
This does not show the loading template however when I navigate to /mypath. (I have setup a delay in route.js/beforeModel to test)
When I navigate to /mypath/loading/ however it will show the loading template.
