No family sharing, and as mentioned only two devices are logged in.
It happens whenever I attempt to watch something on my non apple laptop, and for some reason just after trailers, the screen is black and not streaming anymore. After few refreshing of the page I get this box info about streaming device limits… Always had an issue with watching Apple TV out of the app, but after some struggles (refreshing page) i was always able to use the service, from yesterday it’s totally unusable (once the box appears on my laptop, I’m no longe able to stream on my iPad as well)
