Your LN tip worked fine. I used Wallet of Satoshi from Damus.

But, the zaps sign does not show up on my Damus for anyone. The zaps sign shows up using iris.to, on DuckDuckGo and it looks like, by just clicking it, the default wallet opened is BBW without an option to chose a different one. Nevertheless, if the zaps button is pressed and held pressed, the option to copy the invoice appears in the drop down window
