Just heard back from customer service. By default, Phoenix wallet uses a new Bolt12 lnurl format that hardly any other wallets are compatible with yet. Bolt12 is "just a few months old" apparently. Trying to decide if i should wait a bit or switch to another wallet. Btw, what wallet do you use, and are ypu happy with it?
I am using #coinos. It's custodial, but I only keep 10 bucks or so in it specifically for zapping on #nostr.
I use #amethyst and I link my coinos wallet to #alby via NWC because that lets me zap natively in the amethyst app (without needing to open my wallet outside of the app).
