Testing zaps on this note… we made six attempts to⚡zap this note, at bjorn@minibits.cash, over a period of 20 minutes. All six attempts were successful. Please check on your end to be sure you received. Average zap time was 5451ms (5.5 seconds). We consider this zap time slow... generally, zaps should complete in under two seconds. (Other Nostr users might think your zaps are broken, might not zap you again.) We recommend you receive zaps with a well-connected, cloud-based Lightning node to reduce your latency.
