We identified the problem as an issue with an externally sourced piece of software that is currently down this in turn is causing an issue in determining file length and other important information we need for the media files.
We are now self hosting the external piece of software to ensure this won't happen again in the future so the issue is fully resolved.
Thanks so much for your patience and understanding.
Currently investigating - audio file upload issue where users are unable to upload audio files to publish new episodes/update existing episodes.
