Oh, I think it's working now using my custom domain. It must have been the one click tip settings. I just confirmed I can click the ⚡️ button in my Astral profile and send tips from my custom address to my ln.tips wallet. Feel free to give it a try. 😃
#[6] Do you see my tip link enabled here now? It only seems to work for me if I use a WoS address, not even forwarding from my alias seems to work for this.
