Why is AirDrop stuck on waiting?

Could you please explain why the AirDrop feature on my device seems to be stuck on the 'waiting' status? I've tried to send files to another device using AirDrop, but it's just not going through. Is there a specific reason for this, and are there any troubleshooting steps I can take to resolve the issue? I'm eager to use AirDrop efficiently and would appreciate any guidance you can provide.
