A: Hello, there are downloading problems under some circumstance and we are working on it. However, this is not for all sites. Please contact us at [email protected] to provide the links and screenshots. Also share the log:
vd_server.log
Win: %AppData%\NablaMind\SurFast Video Downloader - Paste it directly into the File Explorer address bar and press Enter to quickly open this folder
Mac: /Users/xxxxx/Library/Application\ Support/NablaMind/SurFast\ Video\ Downloader/vd_server.log

You can try to delete the Chromium in the same folder to see any difference. Wait for your feedback and update.
