How do I get the app out of trial and into Starter
Go into your app and pick a plan in settings. 
Settings > My plan > Change plan
You have to pay for each app separately.
so the first app, it didn’t work, so I started over, so I really should have deleted that first app and started over on “that side”?
Yeah, you can unsubscribe the other app and then sign up for a new plan on the new app.
