If you have one or several iPad apps that are “dark”, still installing, and/or giving you a message saying you need to purchase the app from the app store when you click on it, here is what to do:
If you only have a couple of them, check to see if the app is available in the app portal. If it is, try to install it from there.
However, if you have many:
Take the iPad home. Make sure it is connected to your home network. Plug it in. Leave it alone – don’t even TOUCH it – overnight.
If that doesn’t work:
Bring your iPad by the ARC when you can be without it for several hours – either first thing in the morning, or after 12:30.
