@partypeople Thanks for posting.
We're absolutely aware that it's a MN site issue and not a device issue. But the problem only affects some devices, depending on their specs and how the site is being used.
We're actively trying to fix the issue so that it works on all devices, and for all use-cases, but the challenges involved with that aren't straightforward as the issue is with a 3rd-party system.
You're absolutely right that viewing 1,000 posts per page also showed 40x more data on the previous site, so I wanted to explain why that wasn't a problem and it now is.
On both the old site and the new site, pages with 1,000 posts visible took longer to load because, as you would expect, it takes more time to retrieve 1,000 posts than 25 posts and more time to display them in a browser.
The previous site had much less interactivity on-page. For example, the posting box for messages on the new site has buttons to mention people, add emoji, format text and there are more options for uploading images etc. There are also more interactions on individual posts.
All of this uses more memory, but this doesn't ordinarily cause any problems.
Unfortunately, due to a problem with a 3rd party system, as pages are open for any length of time, the memory usage increases and ultimately the browser forces the page to either crash or reload.
This is why the problem is happening.
We're actively working with the 3rd-party and exploring alternatives to resolve the problem but this is going to take some time.
I can assure you that we're doing everything we can and we'll update as often as we have new information to share.
Thanks 😃
