Hum, estranho. Parece tudo correto.
Hi nostr:npub1syjmjy0dp62dhccq3g97fr87tngvpvzey08llyt6ul58m2zqpzps9wf6wl any idea why I can't zap nostr:npub1w98zr2sevkqle6lmt7u503ewclhzs2cdq94ke4mw7kmpxy2u9y5s6fe9yy? Thanks.
The Lightning icon doesn't even show on his profile.

I think I need to take a deeper look into the differences between lud06 and lud16. His client filled the LN address in LUD-16, but the address appears to be in the lud06 format, so Jumble considers the address invalid.
What is the best wallet to use? I am very confused about LN wallets.
I just installed wallet of satoshi because someone tell me that is the best one.
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
Hi nostr:npub1syjmjy0dp62dhccq3g97fr87tngvpvzey08llyt6ul58m2zqpzps9wf6wl any news here?
Fixed it. I no longer trust the lud16 and lud06 fields in users' metadata. Now, as long as it matches an email format, I'll just treat it as lud16 🤣
Hum, I tried to zap nostr:npub1w98zr2sevkqle6lmt7u503ewclhzs2cdq94ke4mw7kmpxy2u9y5s6fe9yy and still doesn't work.
I just tried, and it works. But since his wallet did not return an address for verification, I cannot accurately determine whether it was successful for now.
Strange, I'm on Version: v0.1.0 (5ad4dfa) and doesn't work
His profile doesn't even have a lightning icon

Now I see sorry. And I was able to zap. Thanks.
This issue might be that his metadata you retrieved yesterday was an older version without the Lightning address. Jumble caches data for a day, hahaha
Maybe lightning address shouldn't be cached, because it's an important data?
It is stored in the kind 0 event along with the avatar and username. Caching it for a day shouldn't have too much of an impact.
We can test it for a while to see if it's necessary to query the latest lightning address before zapping
