Hi, CarolMartini
Could you tell us some details about the upload failed? Like some prompts, it’s advisable to provide some screenshots about it. Maybe there is a network problem with your device, we advise you to check the status of your network, or maybe you can try to change your network temporarily and upload it again. And Wav Format Error might be another reason if you haven’t uploaded your item in 44100 Hz 16-bit stereo.
