Infinite scroll on iOS makes the site unusable.

I've got the setting turned off but apparently this only works on the full version.

This is such a rubbish feature 95% of the time. If I load page "8" it then proceeds to load page "7" immediately and kick me half way up page 8. I went to page 8 on purpose!!!!!

PLEASE LET ME TURN IT OFF ON MOBILE!!!! Otherwise I'll simply stop using this forum it is THAT irritating.

Infinite scroll issues
 
Hello,

I think there are a couple of issues with infinite scroll.
- The like buttons haven't worked outside of the first pages that gets loaded, I think that's a known issue for a while.
- Marking posts as read as you scroll used to work but stopped a few weeks back (maybe 3 or 4). The workaround at the moment is, if there are multiple pages to read, to refresh the page when you get to the last post.
- I haven't been able to reproduce it recently (for lack of a post to reply to) but quick reply also failed last week which I think is related.

The first 2 are true on both desktop and mobile for certain.

I have a feeling that this is linked to javascript code not loading properly via infinite scroll, but I haven't dug any further. I could have a look if you think it might help.

Do you know about these?

Thanks

I haven't ever heard about the last two, so I'll take a look. Do you have particular threads they aren't working on?

It's all threads, I reproduce it on every thread I read since some time early to mid August. I'm signed up to quite a few of them on the BAEC board. I click on the new post arrow in my subscribed threads, and if I have posts on more than the first page I haven't read, only the first one is marked as read, the others aren't unless I refresh when I reach the last page.

I have noticed this frequently as well in recent weeks, feels like maybe around the time of the last update. It *may* be more likely to occur if I navigate away from the page quickly (I am a fast reader :) ) -- maybe whatever code it is that updates the "last read" pointer hasn't had enough time to be triggered or something. It feels like if I let it sit for a while before closing the page then I have this problem less. But also it could just be that I'm refreshing the page and this is placebo effect.

BTW although I feel like the issue I reported here: https://www.flyertalk.com/forum/tech...oad-times.html

has gotten *slightly* better, but only slightly -- for example on a thread of let's say 100 pages, it will randomly load page 30 (say), and you can briefly see those old posts (often years old) but then a second or two later it will jump to the actual first new post that might be on page 99 or 100, which IMO observationally supports my blackbox testing hunch here:

I mention it here because there may be a common thread of, what all the heck is the page load code doing, and might it be over-bloated and time for some optimization...

I think you nailed it. There is a certain amount of time for all pages and elements (both visible and unseen) to load, depending on connection speed.

I would like to encourage the IB developers to take this into consideration, i.e. to remember that people using mobile devices may not always be on the most blazing fast office-quality Internet connection, and thus design and streamline the mobile experience accordingly.

Has there been a change made to scrolling recently? I finally got used to the scrolling past my "40 posts per page" and now it seems that it does not do that any more. I normally go to the last post in the thread and just scroll back from there. Now when I hit the "top" of my current page it stops and I have to click on previous page.

Infinite scroll stopped working for me today as well on iOS mobile.

Only the most recent ten or so posts are shown and the only options buttons are to go to the beginning or the end of the thread

Same here on android mobile, and I noticed it at work on a Windows desktop using chrome on Friday. Infinite scroll is completely down.
