Hi there! I see that when you use the Tubi app on your iPhone running iOS 18.3.1, the video goes black while the sound and captions still work. Let’s figure this out together.

To start, could you tell me if this black screen appears on all videos or just specific ones? Also, have you tried any steps so far, like restarting the app or your phone?

Meanwhile, here’s a simple step-by-step approach to try that often resolves this issue on iPhones:

1. Force Close and Restart Tubi App:
- On your iPhone, swipe up from the bottom and pause in the middle (or double-click the Home button if your iPhone has one) to open the app switcher.
- Find the Tubi app and swipe it up to close it completely.
- Then re-open the app and check if the video plays correctly.

2. Restart Your iPhone:
- Press and hold the side button and either volume button until the slider appears.
- Slide to power off, wait a few seconds, then turn the phone back on.

3. Update the Tubi App:
- Open the App Store, tap your profile icon at the top right, scroll down to see if Tubi has an update available, and if so, update it.

4. Check for iOS Update:
- Go to Settings > General > Software Update and ensure you have the latest version of iOS installed.

5. Reinstall Tubi App:
- Press and hold the Tubi app icon until a menu appears, then tap “Remove App” and confirm.
- Open the App Store, reinstall Tubi, and sign in again.

If these steps don’t fix the problem, there might be an issue with video decoding on your device or a DRM (Digital Rights Management) glitch. We can dig deeper into settings or verify if it’s related to specific content.

Could you please let me know what you’ve tried or if the issue is happening on all videos? That way, I can guide you better.
