I seriously thought I'm alone with this issue, but it seems it's fairly common for people hosting on their own. Same as you guys, it won't sync everything, some communities are even "stuck" with posts from a day back, even though there were many new ones posted.
Kind of off topic question, but I guess it's related? Is there anyone that can't pull a certain community from an instance? I seem to can't pull !asklemmy@lemmy.world or anything from that community, that includes posts and comments. No matter how many times I try, it won't populate on my instance.
EDIT: Caught this in my logs:
lemmy | 2023-06-20T08:48:21.353798Z ERROR HTTP request{http.method=GET http.scheme="https" http.host=versalife.duckdns.org http.target=/api/v3/ws otel.kind="server" request_id=cf48b226-cba2-434a-8011-12388c351a7c http.status_code=101 otel.status_code="OK"}: lemmy_server::api_routes_websocket: couldnt_find_object: Failed to resolve actor for asklemmy@lemmy.world
EDIT2: Apparently it's a known issue with !asklemmy@lemmy.world, and a bug to be fixed in a future release.
Thank you. I took your theme and "nordified" it a bit:

Now it's in line with the rest of my web apps :)
