Videos won't play or keep buffering

1. Check your internet connection. Run a quick speed test at fast.com. If you're under about 5 Mbps, switch to a stronger Wi-Fi network or to mobile data.
2. Download sessions for offline use. If you regularly train somewhere with poor signal (gym basement, parks, travelling), download sessions over Wi-Fi in advance. In the session details, tap the download icon. You can keep up to 10 downloads at once. Find them in Profile, Downloads, even without internet.
3. Restart the app. Force-close and reopen.
4. Update the app. An outdated version may not handle the latest video format — see the app-crash fixes.

Audio plays but no video (or vice versa): usually a codec issue with an outdated operating system. Update your phone to the latest iOS or Android, then update the Traininpink app.
