Hi there! I understand that when you open the JoyMeet app on your Android 10 device using WebKit, it just shows a single advertisement page and won't let you proceed. Let's work through this together.

First, could you please confirm if the app gets stuck immediately after the ad loads, or does it freeze during or right after the video ad? Also, have you tried closing the app completely and reopening it?

Meanwhile, here’s a step-by-step troubleshooting plan to try:

1. Force Close and Reopen the App
- Go to your device Settings > Apps > JoyMeet.
- Tap “Force Stop” to close the app completely.
- Reopen the app and see if it passes the ad screen.

2. Clear Cache and Data for JoyMeet App
- In Settings > Apps > JoyMeet, go to “Storage.”
- Tap “Clear Cache” first. Try opening the app again.
- If still stuck, return and tap “Clear Data” (note: this may log you out or reset some settings).
- Then, reopen the app.

3. Reset Advertising ID (to refresh ad info)
- Navigate to Settings > Google > Ads.
- Tap “Reset Advertising ID.” This refreshes ad identifiers and can fix stuck ads.

4. Check Internet Connection
- Ads need to load from the internet; unstable connections might cause freezing.
- Try switching from Wi-Fi to mobile data or vice versa.

5. Update or Reinstall the App
- Ensure JoyMeet app is updated to the latest version from the app store.
- If updated, try uninstalling and reinstalling the app.

6. Restart Your Device
- A simple restart can sometimes clear system glitches interfering with app ads.

If after these steps the app still remains stuck on the advertisement screen, it could be an issue with ad delivery or the app itself. In that case, please let me know so I can help escalate it or find an alternative workaround for you.

Would you like me to walk you through any of these steps in detail? Also, please share any other relevant details you noticed.

Are you satisfied with the solution I provided so far?
