Since yesterday I have the following issue when I import audio into LingQ (to get the by LingQ AI generated transcript).
After ‘Import’ > ‘Lessons’. Next screen: on the left , under ‘Do it yourself’, the Rd option 'Audio Transcription. When I click on it, in the next screen I import my audio (mp3) I get this error message:
"Unexpected Application Error!
Minified React error #310; visit Minified React error #310 – React for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

Hey developer 
You can provide a way better UX than this when your app throws errors by providing your own ErrorBoundary or errorElement prop on your route."

I have this issue with mp3 files from Youtube videos using the converter Youtube to MP3 Converter (Ad-free) which is recommended by LingQ. But I also have the issue when I import my own converted mp3s from recordings I did with my screen recorder (for example news broadcast in my target language).
