If it happens, but then you clear your cache, does it self-resolve?

No, Chrome on mobile view.

It worked perfectly until late last week (Thursday or Friday I'd say). I will try clearing the cache and report back.

Just happened to me again. Starting in the mobile skin from
https://www.flyertalk.com/forum/subs...n&folderid=all
I clicked on a thread with new messages via the "first new post" link and read the two new messages.

I then went back to the subscriptions page and noticed the thread had not been updated to reflect all the messages had been read. Forced refresh, no change. Cleared cache and forced refresh, no change. Clicked on the thread again and it showed me the same two messages as if they were unread.

Possibly of note: the first unread message was N+1 where N is an exact multiple of 15, which is my default page size (of course the page size only really comes into play on the desktop skin without infinite scroll, but even in infinite scroll it still keeps track of page numbers).

This reinforces my vague recollection (in that I haven't kept notes on details but this seems to fit with my memory) that the problem tends to occur when there are multiple new pages of messages to be read, almost as if there is a "last read" tracker that remembers the last post number that you read, but that for some reason it sometimes only works on the first page and then stops recording when you cross over a page boundary (and maybe my current experience suggests it is also broken if you begin reading exactly at a page boundary)

Anyway just speculating (black box QA is fun) -- could be a total red herring.

The mobile infinite scroll only updating the read message pointer to the last item on the first "page" of new posts rather than the last post you read definitely is a thing and has been an issue for me for a while. If this recognised as a bug and with the upcoming new version being deployed is this big addressed?

I'm getting this, but seems to be related to thread size (I didn't have the problem on threads at 400 posts, but did when they were 2-3,000). I'll report to tech.

It just happened to me on a thread with ~60 posts. I won't swear to this 100% but pretty sure I haven't seen it on any thread that has 15 or fewer posts, where 15 == the "page" size that I have set (for how many posts to show at a time)

That would make a certain amount of sense, I think

Agree, it happens on any size of thread where it is multipaged. So for me like Zorak I have my page size set to 15, where any thread has more than 15 posts the last read message counter is unlikely to update if the last new message isn't on the "page" of 15 where the first unread message is when I enter the thread.

How can I reset FT so posts appear by page instead of continuously scrolling?
 

I'm sure this question has been asked before. I just can't find it and I'm sorry if this is the wrong forum.

Go to “my flyertalk” > go to “settings and options” > edit options > disable infinite scroll

Under the blue tab "My Flyertalk" above this page, I do not have "settings and options." What am I doing wrong?

Use the desktop version of the site, and then you should see your control panel as a fixed menu on the left side of the screen when you go down.

Do you see this https://www.flyertalk.com/forum/prof...do=editoptions when in desktop mode to set the disable infinite scroll setting option for mobile use?

I was always on the desktop version but using the link you gave me, I was able to change the settings. Thank you!

Nudge for IBJoel - is there any acknowledgement from the techs that this is a bug and it's going to get fixed? Thanks!

I'll nudge tech. It's not a reliably reproducible issue and when that's the case, it's difficult for them to do anything about.
