Hi there! I see you're having an issue with money transfer on your MoMo App. Let's get this sorted out together. To start, could you please tell me:

- Are you getting any specific error message when trying to send money?
- Is the problem happening on every transfer or just one particular transaction?
- Have you checked that your account is fully verified?
- Do you have enough funds in your MoMo wallet for the transfer?
- Are you using the latest version of the app on your Android 10 device?

With these details, I can guide you through the most appropriate steps. Meanwhile, a good starting point is to ensure your MoMo account verification (KYC) is up to date as incomplete verification often blocks transfers. Also, confirm your balance covers the transfer amount including any fees.

If you've already checked these, please let me know! Then we can try refreshing the app, retry your transaction, or look deeper into possible network or server issues.
