Hi there! I understand you're having trouble moving forward in the Grant Cash Advance app after accepting the new customer agreement. I'd be happy to help get you back on track.

Could you tell me a bit more about what happens after you accept the agreement? For example, does the app freeze, show an error message, or just not respond? Also, have you tried closing and reopening the app or restarting your device?

In the meantime, here are some steps we can try:

1. Force close and reopen the app: Sometimes the app needs a restart to process new information properly.

2. Clear the app cache: Since you mentioned using a WebKit-based environment on Windows, if you're accessing the app through a browser, try clearing your browser cache and cookies. This can fix loading issues related to updated agreements.

3. Check for app updates: Make sure you have the latest version installed. Updates often contain bug fixes for problems like this.

4. Network check: A slow or unstable internet connection can sometimes cause the app to hang, especially after submitting forms like agreements.

5. Try a different browser or device: If possible, try signing in and accepting the agreement from another browser or device to see if the issue persists.

If you've already tried these steps or the problem continues, there might be a specific glitch related to the new agreement acceptance process. In that case, I can help escalate this for further investigation or connect you with Grant's customer support directly.

Let me know what you've tried and what you observe after attempting to accept the agreement, so I can guide you next!
