How do you "try again later" when it says "audio is temporarily unavailable"?

How do you “try again later” when it says “audio is temporarily unavailable”?

I just created a lesson by pasting in the text and uploading an mp3 of the audio.

It gave me this error on the left side of the screen:

Audio is temporarily unavailable. Please try again later.

How do I try again later? Do I try to attach the exact same audio file to this lesson?

Or do I have to try to recreate it all from scratch (putting in the title from scratch, the image from scratch, the text from scratch, picking the course, etc)?

Can you please send that audio file to support@lingq.com so I can take a look? Thanks.

There is a problem—I do not remember which episode it was…

Could you check from the server side and tell me what the name of the audio file that failed was, and then I can send it to you?

BUT also, what about in general:

In general, when it says “Audio is temporarily unavailable. Please try again later.”

What does it mean?

Try again how?

Am I supposed to reopen the same lesson and reattach the audio file?

Or am I supposed to create a brand new lesson from scratch and do everything over again?

Or is there a “retry” link somewhere I am supposed to click?
