Tangentially, there’s a whole bunch of issues going on with the programming.dev server for one. See at !meta@programming.dev. Lemmy’s upcoming upgrade to 0.19.6 should help - see https://github.com/LemmyNet/lemmy/pull/4623 and https://feddit.org/post/3524876 discussing it.
I did mention that it was only tangentially related. I did not realize though that programming.dev was not all that old. TIL.
