I can no longer upload new lessons (please help)

Today I was going through my normal routine of uploading new study material to lingq, and encountered a problem I have never encountered before. Whenever I attempt to upload something now, a message comes up saying: “external_audio”: Enter a valid audio url" and I am unable to upload it. None of the lessons I upload include audio so I am confused why this is happening.
Any help would be greatly appreciated. Lingq is a big part of my daily studying and I’d love to get back to using it as soon as possible.

Had same problem. A quick fix that I used was just to find a sample mp3 online and enter the url in the box that appears when you click on the “Add URL” button.

For example this URL:

same problem for me too
