It seems intentional that it resumes from where you left off last time (and I think that's actually a nice feature), but I don't understand why the feed not showing up properly isn't considered a bug.
Isn't NIP-65 supposed to work by fetching notes from each write relay listed in my follow list’s NIP-65 models, rather than just connecting to my own NIP-65 relays? That way, whether or not my relays are shared with others shouldn’t really matter, right? Or maybe I'm misunderstanding how NIP-65 is meant to work.
Of course, merging all the write relays from a long follow list and constructing proper filters from the overlaps is probably not easy. So maybe it’s not exactly a bug, but more like an implementation that just isn’t fully finished yet.
