I download a audio file mp3 for the last 2 months the file work fine
But since last night I download the audio file on my galaxy note 8 transfer the file by bluetooth to my apple book pro (2008 model) computer, the last step is to connect the mp3 player to the computer and transfer the file to the mp3 player.
The compuer recognizes the mp3 player as a hard drive so I can transfer the audio file.
I have to use bluetooth to tranfer the file because I don’t have wifi.
Now I get an error message that reads
"File Formate Not Supported"
Was the mp3 player reconfigured to the it refused to play new audio files?
