I tried uploading an audio called “D09SLoop” for a joke horror game. Roblox told me to check if the audio was valid after purchasing, and I tried exporting from Audacity two more times. One as MP3, one as OGG. I refresh the page to see they were being approved, despite the error message. My account has not been charged, and I will attach the audio files.
That’s not how audio uploading works, it’s not about what sounds logical or not. Irrespective of whether an audio exists or not, there is a fee that must be paid before you can upload sounds. Uploading audio without having to pay the fee is an error.
