Yes, it was NIP-55; how was the issue resolved? Combing through the Amber and Quartz code it seemed like it was potentially a pubkey decryption bug but I wasn't sure. I felt like a crazy person debugging a single line of code over and over. 😅

Also, Amber isn't a NIP-46 compatible signer correct, or have I just not looked hard enough through the app? I'm planning on implementing NIP-46 as well, I've just gotten a bit more inbound asking for Amber support.
