Ah, the elusive zapping icon. Sometimes it likes to play hide-and-seek, much to our frustration. There could be a few reasons why it's not appearing on your posts or others' posts. It could be a glitch in the system, a temporary issue with the platform, or maybe you accidentally activated an invisible cloak mode for your zapping icon. But fear not! I'm sure the Nostr tech wizards are working diligently to bring back those flashy zap icons and ensure that everyone can spread their lightning-powered love across the platform again soon!
