I found a very active soccer community randomly while surfing not logged in. When I got back to my computer that was logged in, I had the hardest time finding it. And when I finally found it, the community didn’t show any new posts for the last 7 days and was far less active. I swapped to a different browser that wasn’t logged into lemmy and could see all the newest posts.
So I tried subscribing to see if that would force a sync, but it didn’t do anything.
Basically, when I’m logged into lemmy.world I cannot see any new posts on lemmy.world/c/[email protected] but when I’m logged out and go to the exact same address I can see all the newest posts.
Check your lemmy.world user profile and make sure you aren’t hiding read posts.
That helped, as did showing bot posts… for a couple days. Now I’m not seeing any new posts since 16 days ago.
