Airdrop Cancelled Immediately with no error message visible
When Airdrop fails, a descriptive message would help, rather than a bogus "Airdrop was cancelled" message. Then it would be easier to troubleshoot the problem using the information in the error message. Airdropping a large movie from my iPhone X to my iMac 17,1 with 32 Gigs Ram used to work consistently, but not anymore.
