I’ve tried 2 different music players but the problem was the same in both. I’m currently using Omnia.
Here’s what I do -
I connect my phone to the desktop and, on the phone, select ‘file transfer’. On my desktop, I open the FP folder in Windows File Explorer and drag a WAV file to the correct FP folder. Still in File Explorer, I click that folder to check the song is (theoretically) there. It always is. But when I go to the phone and check the folder that way it never is. And it usually takes at least an hour to turn up.
Can anybody help please?
