Troubleshooting
- No audio after download: re-check output format and try MP3 128 kbps.
- Waveform not showing: preview features may be unavailable for some sources; trimming still works via timestamps.
- File too large: shorten the selection or choose a lower bitrate.
- Download didn’t start: allow pop-ups; click the final Download.
