java.lang.UnsupportedOperationException on RN #98

I've opened an issue on https://github.com/doublesymmetry/react-native-track-player/issues/2187

I'm using React Native Track Player on a TV Box running android 7.1.2

And I'm getting a crash when trying to remove a song from the queue.

Here is the error:

Points to this code

fun remove(indexes: List<Int>) {
    val sorted = indexes.toList()
    // Sort the indexes in descending order so we can safely remove them one by one
    // without having the next index possibly newly pointing to another item than intended:
    Collections.sort(sorted, Collections.reverseOrder());
    sorted.forEach {
        remove(it)
    }
}

Now based on some research I suspect either the function is unsupported in android 7 or another one is its trying to remove from a non-modifiable list.

Any ideas?
