I noticed my devices are not showing content on TV+, instead its showing the generic previews and 'Try it for free' button, if I click that, it says you're already subscribed.
Same. My girlfriend has been battling being signed into Apple TV+, and Settings> Passwords & Security won't load on our phones.
Same deal a few minutes ago..
Can report the same. Manifesting as different errors and behaviors on different devices and os’s.
