When the app doesn't allow you to scan another receipt, it indicates that a receipt has previously been scanned and is currently being processed. This means that the system is already in the process of handling a ticket, and until that process is complete, you won't be able to scan another receipt.
Once your receipt has been processed, if it happens to be rejected for any reason, you'll be given the opportunity to resubmit it. This ensures that any issues with the initial submission can be addressed and corrected.
Additionally, it's important to note that expired promotions will also prevent you from uploading your receipts. This restriction is in place to ensure that all submissions adhere to the specified promotional period, as participation outside of this timeframe is not permitted.
If you find that none of the aforementioned situations apply to your case, it's advisable to reach out to our technical support team for further assistance.
