It’s still an experimental feature and not fully implemented yet. Many of the wallets are not yet supporting it.

Tipping works (lightning:sirius@getalby.com) but publicly reporting the tips (=zapping) is not released, yet.
Am I right that a lnurl address is enough to fully enable tipping. But only NIP-57 enables that they are also reported? So if someone has an address with NIP-57 you can not show how many tips he received, but everything else is working the same?
