Hi! I understand you're experiencing a black screen on the MS NOW app on your iPhone for about 3 seconds before it comes back to the live show. Let's work through a few steps to try to fix this.

First, to help me better assist you, can you tell me if this happens every time you watch live streaming, or just occasionally? Also, is your internet connection stable during these times? Are you on Wi-Fi or cellular data?

While waiting for that info, here are some straightforward steps you can try to resolve this issue on your iPhone running iOS 18.7:

1. Close and Restart the MS NOW App:
- Swipe up from the bottom of the screen and pause slightly to see your open apps.
- Find MS NOW and swipe it up to close it.
- Then, reopen the app and try streaming again.

2. Check for App Updates:
- Go to the App Store.
- Tap your profile icon at the top right.
- Scroll down to see if MS NOW has an update available. If yes, update it.

3. Restart Your iPhone:
- Press and hold the side button and volume up or down button until you see the power off slider.
- Slide to power off.
- Wait 30 seconds and then power it back on.

4. Check Your Internet Connection:
- Run a quick speed test app or just try loading other streaming content to confirm a stable connection.
- If on Wi-Fi, try switching to cellular or vice versa to see if the problem persists.

5. Reinstall the MS NOW App:
- Press and hold the MS NOW icon and select "Remove App."
- Then go back to the App Store and reinstall it fresh. This can fix corrupted app data causing the black screen.

If you've already tried some of these steps, please let me know which ones, so I can suggest more advanced troubleshooting. Also, if the issue happens only during certain times or shows any error messages, that detail would help.

Are you comfortable trying these steps now?
