I think you misunderstood the content because I did not elaborate on the explanation.
I will summarize the contents again and say the following.
The problem I am having is a problem with the latest version of Anki.
There are mp3 files on my card, but when I press the export button, these don’t work.
To make these work again, the only way is to turn off and on Anki or re-import the exported file.
In conclusion, clicking the export button immediately disables the mp3 function.
Please test once.
Current old version 2.1. 26 works fine with no problems.
If you have any further questions about the matter, please let me know.
I look forward to your genius ideas.
please help
