Hi there! I understand that while watching some Viki episodes on your Roku TV, certain episodes kick you back to the home screen. Let's try to get this sorted out for you.

To start, could you tell me if this happens consistently with the same episodes, or is it random? Also, have you noticed if other apps on your Roku are working fine without any issues?

In the meantime, here’s a step-by-step approach to tackle this problem:

1. Restart your Roku device: This refreshes the system and clears out temporary glitches. You can do this by going to Home > Settings > System > System Restart.

2. Check your internet connection: Make sure your internet speed is stable and strong enough for streaming. You could try restarting your router to eliminate any network hiccups.

3. Update the Roku firmware and the Viki app: Sometimes, outdated software causes crashes. Go to the Roku main menu, select System > System Update, then check for updates. Also, revisit the Viki app and see if there’s an update available.

4. Uninstall and reinstall the Viki channel on Roku: This can help clear any corrupted app data. Remove the Viki channel from your Roku, then add it back fresh.

5. Try playing the problem episodes after these steps: See if the issue persists.

If you've already tried any of these, just let me know which ones, and I can help dig deeper or explore other fixes.

Are you comfortable with these steps? I’m here to guide you through them!
