[Humphrey]

That's all well and good, but my app got deleted because they told me an app cannot be a webview of a website.

When I raised an appeal, and proved to them how it was a self contained app, they told me an app cannot be a webview of a website.

When I deleted the website they told me that my app was just a webview of (which it wasn't), and then reappealed, they told me an app cannot be a webview of a website, and deleted my app.

So, the lesson here is: Submitting an app that renders using a webview is a gamble and that Google reviewers don't actually review your app.
