Custom Ringtones
Hello,
Recently I wanted to make a custom ringtone, so I downloaded a file, and converted it + shortened it. It is 23 seconds, and the extension is an .m4r, but when I try to add it to the tones tab on itunes, it does not show up. It recognizes the file(It shows a green plus mark with a blue outline) but does not add it to the tones file. I've checked the file description and it says it is a ringtone. Could the issue be because my Macbook is running a old OS?
My iPhone is running ios 13.1.3, and my mac is running macOS Sierra 10.12.6
