We’re still working to find a solution for the posting slowness in large communities.
We have seen that a post does get submitted right away, but yet the page keeps ‘spinning’
So right after you clicked ‘Post’ or ‘Reply’ you can refresh the page and the post should be there.
(But maybe to be sure you could copy the contents of your post first, so you can paste again if anything would go wrong…)
I came here looking for information on this exact thing and judging by a couple of posts I found through Google on other Lemmy instances, it seems to be a Lemmy.world specific problem with Jerboa. So probably connected to the community slowness?
I’m getting this issue on a mobile browser.
