I wanted to use a custom notification sound but the phone won't allow me to select the file & gives the error message shown in the screenshot. The sound file
was originally an mp3 file but I converted it to ogg just in case the zenfone 6 didn't like mp3's. Any suggestions for how I can use the sound?
The error comes when I use the '+' button & then the file manager to select the file location in the Notifications folder on internal storage. Original file is also attached.
