I have an Dzwonki iPhone 11 with iOS 13.7 (17H35). I want to create a custom ringtone for one of my contacts from a song in my iTunes library. If this is possible, I would really appreciate it if someone could tell me how to do it. I've already created the song fragment and saved it on my desktop (Windows 10 updated) as an "m4r" file, but can't figure out *** I'm a spamming asshole! *** it to my iPhone as audio. I am retired and not particularly tech-savvy, but I can follow the instructions.
