Hello! I understand you're having trouble moving to the payment screen on the Agoda app. To help you better, could you please tell me if this issue happens after you select your booking details, or does the app freeze or show any error messages when you try to proceed?

Meanwhile, here are some common solutions that often resolve such issues within the Agoda app on Windows devices:

1. Restart the app and device: Sometimes, simply closing the app completely and restarting your computer can clear temporary glitches.

2. Clear the app cache: Although cache clearing is more common on mobile apps, since you're using a WebKit browser on Windows, you can try clearing your browser cache and cookies. This removes temporary files that might block transitions between screens.

3. Disable browser extensions: Some extensions or ad blockers may interfere with the booking flow. Disable any extensions temporarily to see if it helps.

4. Update the app or browser: Ensure that both the Agoda app (if it’s standalone) or your WebKit browser is updated to the latest version.

5. Try another browser: If you still cannot proceed, try accessing Agoda on a different browser, like Chrome or Edge, to check if the issue is browser-specific.

6. Check payment method issues: Sometimes payment gateways require additional authentication such as 3D Secure verification, which might block progress if unsupported. Verify your payment method is accepted on Agoda.

If none of these work, I can assist you with more advanced steps or help contact Agoda support to investigate further.

Did you notice any error messages or did the screen just not load? Also, have you tried any of these steps already? This will guide me to tailor the solution best for your case.
