New certification requirement?

Just watching Frasier on Paramount Plus. I'm watching in the UK, so I'm assuming the onscreen certificate I'm getting is for my territory: https://www.paramountplus.com/shows/video/r5RCWEka_j30hkpuycLLWpp1umNtzmfR/

It's 12+. Which doesn't appear to be on the system.

There's a 12A, but that's slightly different... that means someone aged 12 can watch if they're with an adult. 12+ suggests 12 and above?

Or maybe not...?
