Only clients such as Amethyst, Coracle, Nostrmo, etc., that support NIP-17 DMs, can receive messages sent from 0xChat. Also we recommend using NIP-17 DMs instead of NIP-04 DMs, as NIP-17 helps hide your metadata, enhancing your privacy.
Ah, ok. I was wondering why that was happening. Hopefully the next version of @primal will include that as well. @miljan
