Hi there! I understand you've been having trouble with Water Splash app not giving you rewards or arrows for over two months now. That definitely sounds like an issue that needs attention. To help you better, could you tell me if this problem happens every time you play, or only sometimes? Also, have you tried any troubleshooting steps already, like clearing cache or reinstalling the app?

In the meantime, here's a step-by-step approach you can try to possibly resolve this:

1. Clear App Cache and Data: Sometimes corrupted cache or stored data might cause reward issues. Since you're on Windows and using a WebKit-based browser, try clearing the browser cache. You can do that by going to your browser’s settings > privacy or history section > clear browsing data > choose cached images and files.

2. Restart the Browser and Device: Close the app/browser completely, then restart your computer. This refresh can fix minor glitches.

3. Check for Game Updates or Server Status: The app development team acknowledged a known issue causing missing arrows and rewards and said they are working on an update to fix it. So the problem might be on their end too1.

4. Try Re-logging into the App: Log out from the app and log back in. This sometimes re-syncs your rewards and progress.

5. Check for Browser Compatibility: Although the app should work fine on your Windows 10 WebKit browser, try accessing Water Splash on a different browser like Chrome or Edge, if possible, to see if rewards start showing up.

If none of these help, it might be necessary to wait for the official update from the developers or contact their support directly for a more personalized fix.

Does this help so far? If you’ve already tried any of these, please let me know so I can suggest the next steps.
