Because primal hasn't yet cached the note to serve it up from its centralized system.
Thoughts on why I might not see certain responses on nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg but I do on nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 ?
Just started exploring multiple clients to see the different UX.
Example: I only see this reply on Damus but not primal

Yeah and when it has, if ever, it's too late for the user to recognize. Which sucks tbh.
