Hi there! I understand you're facing an error 4194824 when trying to play videos on the Canela.TV app on your Samsung TV for the first time. Let's get this sorted out together.

To start, could you tell me if you've tried any actions so far like restarting the app or the TV? Also, do you know if your Samsung TV’s software is up to date? This can often affect app performance.

Meanwhile, here are some steps we can try:

1. Restart the TV: Turn off your Samsung TV completely, unplug it from the power source for about 1 minute, then plug it back in and power it on. This can clear temporary glitches.

2. Check for TV Software Update: Go to Settings > Support > Software Update on your Samsung TV. If there’s an update available, install it. Updated firmware ensures apps work smoothly.

3. Reinstall Canela.TV App: Navigate to the Apps section on your Samsung TV, find Canela.TV, uninstall it, then reinstall it. This clears the app’s cached data and might fix the error.

4. Check Internet Connection: Make sure your TV is connected to a stable internet network. Sometimes video playback fails because of connectivity issues.

5. Clear App Cache (if possible): On some Samsung TV models, you can clear cache for apps under settings > apps > Canela.TV > Clear Cache.

If after these steps the problem persists, please let me know. We can then explore more advanced troubleshooting or check for any service-related issues on Canela.TV’s side.

Are you able to try these and tell me how it goes?
