Hi there! I see you're getting a "cash not allowed" error on the MD Lottery app. I’d be happy to help you get this sorted out. To better assist you, could you please tell me:

- When exactly do you see this error? (e.g., when scanning a ticket, trying to cash out, or at another point)
- Are you trying to redeem a scratch-off or a different type of ticket?
- Have you tried scanning the ticket multiple times or from different angles?
- Is your MD Lottery app updated to the latest version?

Meanwhile, here are some initial steps you can try to resolve the "cash not allowed" error:

1. Check Ticket Eligibility: Sometimes, tickets that are part of a pack not registered properly or tickets meant only for retail redemption may show this error. Verify that your ticket is valid for cashing through the app.

2. Proper Scanning Technique: Turn your phone sideways (landscape mode) and align the scanning red line exactly across the QR code on your ticket. This often helps the app read it correctly.

3. Update the App: Make sure you have the latest version of the MD Lottery app installed from the Google Play Store.

4. Clear Cache: Go to your Android Settings > Apps > MD Lottery > Storage, and clear the app cache to improve performance.

5. Try Scanning at a Retailer: If the app still shows "cash not allowed," try taking the ticket to a physical lottery retailer. Sometimes tickets can only be cashed in-store.

If you’ve already tried these steps or are unsure, please let me know what you’ve tried and any other details. That way, I can offer more tailored guidance! Are you able to share the exact message or screen you see when the error comes up?
