Solution 3: Check for App Updates

Audio sync bugs are often fixed in newer app versions.

Android:

2. Tap your profile icon
3. Select "Manage apps & device"
4. Update CENTR if available
5. After updating, try the video again

Solution 4: Try a Different Video

Check if the issue is with one specific video or all videos:

• Play a different workout video
• If other videos are fine: Report the specific video with sync issues to [email protected]
• If all videos have sync issues: Continue to Solution 5

Solution 5: Check Internet Connection

Slow or unstable internet can cause audio sync problems.

• Run a speed test at fast.com (need at least 5 Mbps)
• Switch from mobile data to WiFi if available
• Move closer to your WiFi router
• Close other apps using bandwidth
• Restart your router: unplug for 30 seconds, plug back in

Solution 6: Delete and Reinstall the App

Important: Your data is saved in the cloud. Reinstalling won't delete your workout history or subscription.

iPhone:

1. Delete the CENTR app completely
2. Restart your iPhone
3. Reinstall from App Store
4. Log in with your credentials
5. Try playing the video

Android:

1. Uninstall the CENTR app completely
2. Restart your device
3. Reinstall from Google Play Store

Try Downloaded Videos

If streaming videos have sync issues, try downloading:

1. Connect to WiFi
2. Find the workout you want
3. Look for a download icon or option
4. Download the video completely
5. Play the downloaded version offline

Downloaded videos often play more reliably without sync issues.
