Two-page test
Open the home page, then any title page. When both appear, RedStream is up and running.
Slow loading
Reload the page, clear the cache or open RedStream in another browser. Changing from Wi-Fi to mobile data, or the other way round, often speeds things up.
Playback trouble
If a film buffers, check the streaming service's own help or status page, since the video comes from that service.
