You’re right! I’m still figuring out a solution. Moreover, it seems that many relays don’t accept protected events. I’m not sure how to distinguish between those that do and those that don’t.
Loving the update to Jumble.social nostr:npub1syjmjy0dp62dhccq3g97fr87tngvpvzey08llyt6ul58m2zqpzps9wf6wl!
One thing I am noticing, though. Now that "favorite relays" load in the right-side panel, you cannot select to send a note to only that relay. You first need to add it to a relay set, so it will show up in the left-side panel, and then Jumble will display the toggle to send your note only to that relay.

Do relays advertise which NIPs they support? That one is what? NIP-70?
