I've been constantly running into issues of stale content and errors fetching post on lemmy.ca the past couple of days.
While scrolling on my client (Sync), I keep seeing errors about fetching new posts and have to click retry a few times to fetch more posts. At times I have to retry 6-7 times. Additionally, it seems like I'm seeing posts I've already seen a lot from the past more quickly than I'd expect in "Hot".
I tried changing to a different instance and at least the first issue was immediately resolved. Posts were fetched quicker, and I didn't get any more errors while fetching posts.
I haven't run into this on alex.lemmy.ca on desktop (yet), so it's possible that it's an API issue. It's also possibly a Sync bug.
I suspect there's been a recent performance/federation regression, could one of the admins confirm/deny my suspicions? Totally not a problem if it's not something that can be fixed right away, just wanted to bring it to y'all's attention.
Edit: although the screenshot mentions posts being filtered, I don't have enough filters to completely prevent fetching new content
