I recently took the paid upgrade and I’m struggling to get any images in my listing. Normally I always drag and drop from the mac built in ‘Photos’ app - I have also recently upgraded to the Sierra OS on my imac
The only way I can do this is by dragging images from my photo app to the desktop and in to GS - This isn’t practical as I have around 100 listings with around 15 images each and I would really expect to be able to do a simple drag and drop function.
