Same. NIP-46 is rough and inconsistent, unfortunately. Would be really nice if nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft could give us Android folk the ability to use NIP-55 instead.

I finally was able to sign Olas events with Amber today, properly; via NIP-55. It won’t be included in the next release as the next one is focused on much better wallet and connectivity improvements; but the one after that will be 100% about Amber. Both should be out before Thursday.
