iOS 12 screen time and localhost

We have developed an eBook application that uses the webview to render content from local file system. Now since the content contained HTMLs with embedded audios and videos, we had to create a local server, that listens on a port and the application can simply connect to 127.0.0.1 to fetch the data.

With the screen time restrictions, apple has blocked 127.0.0.1 unless it is explicitly added to the allowed websites list. We have institutes using this setting and they are unable to update screen time setting to allow 127.0.0.1 to list of allowed websites via the Mobile Device Management tools.

My question is:

1) Is there a way to specify some website in app's manifest so it overrides screen time restriction?

2) Is there a way for MDMs to add 127.0.0.1 to allowed list

A quick response will be greatly appreciated.
