Hi there! I understand that when you try to watch content on the MeritTV app on your iPhone, it only plays the trailer instead of the full show or movie. Let’s get to the bottom of this together.

To help me assist you better, could you let me know:
- Is this happening with all content or just specific titles?
- Are you logged into your account and is your subscription active?
- Have you noticed if this occurs right away or after some parts of video playback?

Meanwhile, here are some initial troubleshooting steps we can try on your iOS device (version 18.6.2):

1. Check Your Subscription Status: Ensure your MeritTV subscription is current, as a non-active subscription might restrict full content access and only show trailers.

2. Sign Out and Sign Back In: Sometimes refreshing your login session helps. Open the app, go to settings or your profile, sign out, then sign back in.

3. Clear App Cache/Restart App: Double-press the Home button or swipe up to see app previews, then swipe the MeritTV app off the screen to close it. Reopen the app and try again.

4. Update the App: Check the App Store for any available MeritTV app updates. Running an outdated version can cause playback issues.

5. Reinstall the App: Delete the MeritTV app from your device, then reinstall it fresh from the App Store.

6. Check Network Connection: Ensure your Wi-Fi or cellular data is stable, as poor connectivity can cause loading errors defaulting to trailers.

7. Toggle Video Playback Settings: If the app has settings related to video autoplay or previews, try disabling those temporarily.

If you’ve tried these already or the problem continues, please let me know what you’ve done so far, and if you have any specific error messages. We can then explore deeper options or check if there are any known app-side issues.

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