Doesn't interoperate well - Lemmy
lemmy.ml
It seems that Lemmy instances don’t work well with each other. Following a community from another instance is finicky, and after following, threads and comments still don’t show up unless you manually pull each individual URL into your own instance.

The post count for some threads seems to be off, and there seems to be a problem with notifications for other instances.

Is the latter is a result of the recent increase of traffic on Lemmy.ml or a problem of the other instance?
