Keynote 6.2 drops images when moving files between devices - every time
I've bene using Keyniote 6 throuh 6.2 extensively and I've found that saving works perfectly, but if you copy a file from one device to another - via any method (USB Key, Wetransfer, SendBiGFile, a hard disk, even AirDrop between two Mac's, it always drops a few, but not all, images.
You see this when you open the new presentation, you get no warning errors because the thumbnails are preserved, but you'll get a "X" graphic in the main display.
There is a workaround for this which is to ZIP the file first before transferring it. If you use Compress from the Apple shortcut menu to make a ZIP file before you do the move then it is always OK, but if you don't, it will always drop a few pictures. Obviously this is on a reasonably large file - say 50 slides or more.
The workaround is a little cumbersome, so a fix would be really appreciated.
