Open Downloader and enter this URL (you will need to find a current live link from the developer's GitHub – do not use random shortlinks). As a rule, search Google for "SmartTubeNext GitHub releases" to find the current stable build (which functions like 617724).
Once downloaded, click "Install" in the Downloader app.
Search for "SmartTubeNext GitHub" instead of chasing the 617724 APK. You will get the same ad-free experience, plus newer features like HDR support, improved voice search, and regular bug fixes—all without the security risk of downloading an outdated "hot" file from a shady website.
