Not sure if this is isolated to me, but when sorting by Active, my Subscribed, Local and All feeds pretty much don’t change for multiple days. I have to sort by New, Hot, etc. to get new content, but even those feeds stay somewhat constant.
Is this a problem with how the Lemmy feed algorithms work? Or is it a queueing issue, like how Mastodon refreshes timelines?
This is an issue that the dev team is actively working on and (I believe) it’ll be a part of the 0.18.0 release.
There’s a hacky workaround some admins in the matrix chat implemented @TheDude@sh.itjust.works – set a cron job to restart your lemmy back-end every hour or so. Not sure what the impact would be on a bigger instance like this but the restart only take a few seconds on my smaller one and it keeps my feeds fresh.
