Also still seeing lots of backend timeouts and slow responses, plus I somehow got logged out again (I logged back in after a few tries).

I begin to hate Lemmy's web front end, because it uses so much asynchronous network stuff. The success path works somewhat ok when things are fast, but when things are slow (even if you don't hit an error), you can never tell whether the screen state has caught up to the server state. We need an old fashioned synchronous front end, so if the browser says that a page has finished loading, you can know that what you see on the screen is the final state of the page.
