Audio did not upload

I had no error message when I uploaded the audio for both the little German lesson I shared earlier on. Ytk031 has now pointed out that there is no audio playing.

I have followed the usual procedure, so there may be a bug.

I have no problem listening to the audio> Others?

No.I is fine, but the audio files of No. 2 and No.3 are not working.

ditto

It’s working again. Thank you!
