Weird, I just checked again since I normally have it off and it is working for me. I have enabled Mark post as read, mark post as read on scroll, dim read post, and under account settings show read post disabled. This is on a pixel 6.

I was afraid of that. Wanted to do a whole play through with the new weapons. Oh well

I’m going to be able to start this on Monday, and I really don’t want spoilers except one thing. If I start a new game will I have access to the new weapons prior to entering the DLC area?

Works for me. Go into account settings and disable show read posts.
