Hey there Loquendo, we also couldnt zap you, two important things need to put into consideration:

1 - Generating a wallet is only for sending sats

2 - Linking wallet with your profile or in other word updating your metadata with your Lightning Address is for receing sats.

Please make sure this two things are well assigned so everything can function properly. If you found any issues or confusion feel free to contact us anytime 🙏
