Right. I'm suggesting you change your LN Address in nostr to avichand@npub.cash over alby for privacy reasons.

I did and I wasn’t able to zap people 😐
avichand@npub.cash is for receiving zaps, not sending them. You can send from any client you wish. On my phone when i tap on avichand@npub.cash, and invoice gets generated on npub.cash server, and that triggers the client e.g. Android, iOS, etc, to open an app, e. g. eNuts so that i can pay the invoice
