Error messages for non-compatible features would be nice too.
This note includes a feed, it opens empty on Damus, has just the nostr:addr… on Primal.

Designers how might we help guide users whose nostr app just failed to find a note?

Thanks nostr:npub1a7n2h5y3gt90y00mwrknhx74fyzzjqw25ehkscje58x9tfyhqd5snyvfnu
I think this points to handling unknown event kinds, and recommended app handler NIPs, which damus has yet to implement.
Nice work nostr:npub1n0sturny6w9zn2wwexju3m6asu7zh7jnv2jt2kx6tlmfhs7thq0qnflahe !
Thanks nostr:npub1a7n2h5y3gt90y00mwrknhx74fyzzjqw25ehkscje58x9tfyhqd5snyvfnu and nostr:npub1zafcms4xya5ap9zr7xxr0jlrtrattwlesytn2s42030lzu0dwlzqpd26k5, this is indeed handling of unknown event kinds, I added this after nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft suggested it in nostr:note16pgkeuxvkl3y8c7zgn9zvnn8w4xwqals9henwag5edez3gx8e9wqm33qep
More clients should implement this, its one of the few ways we leverage the current kind-1 network effect to grow the Other Stuff
