I first consulted the help via the Google Home app. There I was advised
to reset the Chromecast to factory settings. After further Googling I
ended up on this site. It's nice to read here that it's a global
problem, but I keep reading that you should...
Hopelijk wordt het probleem snel opgelost, ik heb al teruggezet naar
fabrieksinstellingen.Hopefully the problem will be solved soon, I have
already done a factory reset.
