So I found Ara Winton's (sp?) article on using a custom mp3 ringtone on my brand new Pixel 4 with Android 10 and none of the instructions have the remotest resemblance to what I'm seeing when I try to use them. And that article is only 2 months old. The downloaded mp3 is in my Download folder in Files on the new phone. I can select it, but I can't figure out how to move it into the Ringtones. I am doing a system update as I type this so there's no rush. But if anybody can give me steps for the very latest OS release I would really appreciate it.
