Yeah, again: Which wallet do you use?
Discussion
I had already answered this:
I am using Unstoppable wallet.
Yeah, I see. Don't know that wallet, but it seems it only supports on-chain transactions and not the lightning network.
If you're on Android you could try Phoenix.
What Kc said. Download Phoenix wallet.
Once the app is installed, open it, tap receive on the bottom left, and use that address in Alby. 🤙
