If the point of PowerApps is to promote building of "Enterprise" Apps, then surely you need to have access to Sharepoint Document libraries that only authenticated Users can access.
Currently you can only view PDFs that reside in libraries that allow anonymous access, quite pointless in an Enterprise environment. That makes this feature useless for most of us.
This one feature would really open a whole lot of possibilities in Enterprise scenarios, especially when trying to wean Users off e-mail oriented workflows.
