Transferring purchased AAC files from Music to Shokz OpenSwim
I can transfer (drag and drop) some purchased files easily. But some I can't. And when I try to do so, I see a red badge with the number one on the file I'm dragging. Does anyone know what the badge means, why I can't transfer some files, and is there any way to know that a file isn't transferrable before I buy it? I don't want to waste money on a bunch of files that I can't listen to using my OpenSwim headphones. Many thanks for your help!
