There’s clearly something wrong all these inbetween mitigation steps
don’t work there’s a bug with the app no matter what device your on, no
matter what version of the app you have. only Netflix is causing a
problem.
Same problem here with my devices. They clearly made updates to either
the Netflix API or the home app that now can’t authorise the login - I’m
presuming it’s a bug in the system that they will be addressing and
resolving swiftly.
