Such bad support for Google chrome its a joke, I have super fast broadband, but try to cast from your phone to a TV and get use to buffering, try and screen mirror from your phone to a Tv and it's a blank screen, security options block it. Yes I have the latest android firmware, yes I'm on an S21ultra, yes my Internet speed is 150mbps... but uninterrupted casting with this app...Impossible. As suggested I'm updating my review, to one star from two, and will not be renewing my subscription.
