Hi! I’m Pierre. Sorry to hear you’re having trouble registering and submitting your Play Predictor results on the Chelsea Official App on your Android device. Let’s see if we can get this sorted out together.

To start, could you tell me a bit more? For example:
- Are you getting any error messages when you try to register or submit?
- Have you successfully created an account on the app before, or is this your first time trying?
- Are you connected to a stable internet network (Wi-Fi or mobile data)?
- Have you tried restarting your device or reinstalling the app?

Meanwhile, here’s a general step-by-step approach that usually resolves such issues on Android 10 devices using WebKit browser technology:

1. Update the App: Ensure your Chelsea Official App is updated to the latest version from the Google Play Store. Sometimes Play Predictor functions depend on the latest app updates.

2. Clear Cache and Data:
- Go to your device’s Settings > Apps > Chelsea Official App.
- Tap on Storage, then Clear Cache and Clear Data.
- This removes any corrupted temporary data that might be causing issues.

3. Check Network Connection: Switch between Wi-Fi and mobile data to confirm the issue isn’t network-related.

4. Allow Permissions: Confirm the app has all necessary permissions enabled:
- Settings > Apps > Chelsea Official App > Permissions.
- Enable permissions related to storage, network, or anything applicable.

5. Try Registering and Submitting via the App Interface:
- Open the app, tap Explore menu > Play Predictor.
- Follow registration prompts carefully.
- Submit your predictions before the deadline.

If after these steps you still can’t register or submit results, it might be related to a temporary server issue or app bug that Chelsea FC is addressing. I can help escalate this if needed or suggest contacting the Chelsea app support team directly at [email protected].

Let me know if you’ve tried any of these or if you see any specific error messages, and we’ll take it from there! Are you satisfied with the solution I provided?

No error messages, tried succcessfully before (last season), stable wifi, reinstall did not help

Thanks for the extra details! Since you mentioned there are no error messages, you had success last season, your Wi-Fi is stable, and reinstalling the app didn’t help, let's try a couple more targeted steps.

1. Force Close and Restart the App:
- Swipe up from the bottom of your screen to open the app switcher.
- Find the Chelsea Official App and swipe it away to fully close it.
- Then open it again and try registering/submitting.

2. Try Using a Different Network or Browser:
- Sometimes an unsecured Wi-Fi or specific browser engine can cause issues. Even though you have stable Wi-Fi, switching to another network (like mobile data) or trying to access Play Predictor through a different browser might help.

3. Check for App Updates:
- Open the Play Store and check if there’s a new update to the Chelsea Official App that could fix known bugs.

4. Clear Browser Data (if accessing Play Predictor via web in WebKit):
- Since your device uses WebKit, clearing cache and cookies for that browser might help if the Play Predictor is accessed through a browser interface.

If none of these work, the issue might be on Chelsea’s app backend, as other users have reported similar intermittent problems around this season’s launch. In that case, contacting Chelsea app support directly at [email protected] will ensure they’re aware and can offer a fix.
