Hi! I’d be happy to help you with the issue of the Kmart portal not opening after entering the OTP. To get started, can you tell me a bit more?

- Are you using the Kmart app or accessing the portal through a web browser on your Windows 10 device?
- Do you receive the OTP successfully and only face the problem after entering it?
- Have you tried refreshing or reopening the portal after entering the OTP?
- Is there any error message that appears, or does the portal just stay blank/not load?

This information will help me guide you through the best possible steps. Meanwhile, here’s a basic checklist we can start with:

1. Clear Browser Cache and Cookies: Sometimes stored data can interfere with portal loading. You can do this in your browser settings under Privacy or History.
2. Try a Different Browser: Since you’re on a Windows device, consider trying another browser like Chrome or Edge if you’re currently using one browser.
3. Disable Browser Extensions: Some extensions (like ad blockers) might block parts of the portal from loading.
4. Check Internet Connectivity: Ensure your connection is stable, as interruptions might prevent the portal from fully loading after OTP verification.
5. Make Sure the OTP is Entered Correctly: Double-check the OTP digits and watch out for expired codes (they usually have a short validity).
6. Restart Your Device: Sometimes a simple restart can resolve browser-based issues.

If you have already tried the above, please let me know what you’ve done so far so I can suggest the next steps tailored to your situation.
