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features like HDR support, improved voice search, and regular bug fixes—all without the security risk of downloading an outdated "hot" file from a shady website.
Open Smart YouTube TV. Go to Settings > Login. It will give you a code. Go to google.com/device on your phone, enter the code, and approve. Your subscriptions and history will sync.
Stream smart, skip the ads, but remember to support the creators who make the content you love.
