Custom notification sound

[john_kissane]

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.

@john.kissane
Did you try "Clear storage" to "Media Storage" system app?
Then restart phone and check again.

Yes that made no difference. The only thing I found that worked was to copy the mp3 file into the Slack notifications folder. Probably would have worked with the Viber notifications folder as well come to think of it.

Really strange 😞
