This is an odd problem to describe.
I can scroll through about 20 posts and then the feed will “hang”. Once those 20 or so posts finish loading thumbnails, additional older posts will be loaded.
This is not as noticeable on fast connections, but causes significant lag on slow connects. There is no immediate indicator that Connect is still loading newer post data when you hit the end of the feed cache/buffer. (It feels like feeds have been split into “pages” and after 20 or so posts, there is a delay when hitting another “page”.)
Thanks for attempting to read this shitty description of a problem. I tried.
Edit: The feed will actually get “stuck” sometimes. It’s common for me on “all”. I had 800mb in cache and just cleared it. It’s got a little better for some reason. I can get close to 50-60 posts before the feed pauses or hangs.
Definitely started noticing this lately scrolling All. It hits a page boundary and then refuses to load any more.
