This is not a wallet issue. Maybe the location where the client you use saves the ln address is incorrect, or maybe I misunderstood. The zap feature of Jumble is still in the testing stage, so it's probably my problem with a high probability. I will check it carefully tomorrow.

Is this a opensource project, can I have a look?
Of course https://github.com/CodyTseng/jumble
But my code might be a bit messy 🤣
The website of the beta version is https://beta.jumble.social
