I started to notice that my posts get no interactions at all and that a lot of communities seem to be empty. At first I thought that it’s just the effect of Lemme. ee shutting down, but after checking some of the communities from my current alt account I started to notice that .Dev does not pull the latest posts and does not federate my posts.
I had the same issue on my single user instance after a Lemmy update last week. It fixed by itself, but it took a few hours, like the entire night.
Computational power or network bandwith was not an issue.
