App Fails to Launch with this Plugin Installed.

[mino922]

I am trying to use this plugin to fix an issue I am seeing in my Ionic app. Here is the issue thread I opened on the Ionic repo

With this plugin installed, I receive the following error in xcode when running on an iPhone 6s simulator.

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<WKWebViewConfiguration 0x6040001ef700> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key _requiresUserActionForMediaPlayback.'

This is a bug of a different plugin:
4 *** 0x000000010c014bf6 __43+[APPBackgroundMode swizzleWKWebViewEngine]_block_invoke + 358

^^

looks like it is the background mode plugin

I didn't use this plugin.

I need to open new issue for my error?
