I used a nevent with an hint:
> many clients don't put a relay in the nevent string
This is crazy.
it requires nevent strings to have at least one relay inside, and many clients don't put a relay in the nevent string -- that's why I made this tool which, among other things, lets you manually add relays to your nevent strings: https://supertestnet.github.io/nostr-helpers/

I saw this today, publishing a longform note and the client didn’t embed any relays. Very surprising.
