Hi there! I understand you're seeing the green circle start and stop about every 10 seconds while using the Frndly TV app on your iPhone running iOS 18.6. That sounds like the app is buffering frequently. Let's work through some steps to get this smoothed out for you.

Here’s what I suggest:

1. Check Your Internet Connection:
Make sure your iPhone has a strong Wi-Fi or cellular signal. If possible, try switching between Wi-Fi and cellular to see if one is more stable.

2. Close Other Apps and Devices:
If multiple devices are using the same network right now, or you have many apps running on your iPhone, it can cause buffering. Try reducing the number of devices using the internet and closing unused apps.

3. Restart the Frndly TV App:
- Swipe up from the bottom of your screen (or double-click the Home button) to open the app switcher.
- Find the Frndly TV app and swipe it off the screen to close it completely.
- Relaunch the app.

4. Restart Your iPhone:
Sometimes a quick reboot can clear up temporary issues.

5. Update or Reinstall the App:
- Go to the App Store and check for any available updates for Frndly TV; install if available.
- If the issue persists, delete the app and reinstall it.

6. Clear App Cache (If Available):
While iOS doesn’t have a direct cache clearing option per app like Android, reinstalling the app essentially clears the cache.

7. Check for iOS Updates:
Even though you’re on 18.6, double-check that no updates are pending in Settings > General > Software Update.

8. Limit Background Network Usage:
- Go to Settings > General > Background App Refresh, and turn off the feature for apps you don’t need refreshing.

If after these steps the green circle or buffering continues, it could be due to network issues or temporary server-side problems on Frndly TV’s end.

Would you mind letting me know:
- Is your iPhone using Wi-Fi or cellular during streaming?
- Are multiple devices currently connected to the same network?
- Have you tried any of the above steps already?

This info will help me tailor the next steps for you.
