Same here, can't comment on this post at https://old.lemmy.sdf.org/post/8216559
TBH I have largely given up on this instance. It's getting on for a month with federation problems and an ill-advised upgrade to an incompatible pre-release Lemmy version that locks out mobile apps. No attempts to fix, no communication that I have seen. This is the sort of stuff you expect/do on a homelab instance, not something intended for general use.
