Can't send key commands to apps without "Bring app to front"

For some reason my BTT can't send any key commands to apps without the "Bring app to front" checkmark being enabled. I would really like to be able to send commands without having to have that window switch back and forth. I checked the Security>Accessibility settings and BTT is checked. I don't think it's ever worked for me. Is there some other setting I need to enable to make this work?

unfortunately this needs to be supported by the app, especially newer apps often don’t implement support for background shortcuts anymore - there is no way to workaround that. (sometimes using Apple Script instead of shortcuts will be possible)

Ah, ok. I'm using it with Chrome, Movist Pro, and VLC.
