I had the Reddit Sync Pro lifetime thing so I just kind of figured it was because of that, but I straight up haven't seen a single ad. It's not like I have an ad blocker on or anything. How weird!
Sync for Reddit and Sync for Lemmy are separate, so the license and all don't transfer. You'll see ads sooner or later if you didn't do anything to block it.
