I am trying to send some docs to my MacBook through Airdrop. Problem being, I have tried almost all suggested troubleshooting, tried restarting systems, took care if the devices were having DND mode on, or were on Sleep, the Bluetooth is also shown connected. But still the Airdrop of either of the devices is not showing the other device available in their respective Airdrop section. This has happened quite a lot of times with me, since past many months. 4/5 month wrt delay in connectivity. Please suggest why it could be happening and what can be done to let Airdrop work fast.
