Yes I do have a Premier Membership.
I rarely look at the Home Page listing of new posts so I've never noticed the graying-out of previously displayed posts.
My first post was in regard to the portion of your post where you were referring to the New Stories and Updates pages and said:
The New Stories / Updates pages behave differently, stories / chapters are shown there even if the timestamps say they have only been up for a few seconds. If anything stories are not greyed-out when they should be, not a big deal.
Have you ever seen the stories listed on those pages grayed-out. I haven't.
The following isn't clear to me.
This is something which I have been noticing for quite a while now and it only affects the home page.
- I see now that a new chapter was posted at 17:16
- When I refreshed the home page at 17:21, that chapter was not shown.
- When I refreshed the home page at 17:49, it was shown "greyed out" because it had been posted before the 17:21 refresh.
Your OP was made at 4/1/2018 9:03:04, so I conclude that your statement "I see now that a new chapter was posted at 17:16" was based on what you saw and means you are referring to a post made at 3/31/2018 5:16 PM (17:16) since the 3/30/2018 posts are long gone. The problem with my conclusion is, there is no 3/31/2018 5:16 PM (17:16) post on the Home page.
ETA: I have to conclude that in your example the times were not actual times but made up to illustrate what you recall seeing.
