Why does AirDrop fail so much?

I've noticed that AirDrop often fails to work properly. Could you explain why this happens so frequently? Is it due to a technical glitch in the software? Or is it related to the devices' compatibility? I'm curious to know if there are any specific steps I can take to troubleshoot and resolve this issue. Additionally, are there any known updates or patches that Apple has released to address this problem? It would be helpful to have a clearer understanding of what causes AirDrop to fail and how I can fix it.
