The s22 is in the same situation. Earlier I saw someone get a reply from samsung support saying the s22 won't get it. So my best guess is that means the tab s8 won't either
(I know we're messing but I felt my source might be helpful)
Nah, we don't actually get any info or access that you don't have access to. I'm literally just a normal person with google, except I have a badge to say I usually know what I'm talking about
