Airdrop suddenly stopped working to transfer mp4's from Imac to phone
I've been doing this since forever. Mp4 exported from Premier to destop to iphone. Now it's saying "Failed to send" Save to airdrop? WTF. The file size is 5mb and I haven't changed anything from the 1000 other times I've done it. I've looked online and tried many different things but nothing is working. Please help?
iMac 21.5″, macOS 10.13
