Reply from Fandom (so far): Hey there,

Thanks for contacting Fandom Support. There actually is a cookie that saves the 'viewed' state, and I'm not aware of any specific reason it would not be working for individual users, unless they are blocking or clearing their cookies.

If you're in contact with affected users, could you ask them to contact us directly?
