That’s a very specific use case that would need you to provide more information, like what app are you using and what trackers are being reported, and that I particularly don’t know if I can help you with.
Maybe if you post said information, someone else can help you.
Edit to add: it is very likely the tracking is being done by the app itself, or when accessing an external link, or embedded content from the app, the app is not protecting you from other trackers, as lemmy.world itself is not tracking you
I use Lemmy through apps. My firewall sometimes detects different trackers when using apps.
