This usually happens after iOS or Android updates. Clear the app cache through your phone settings, then reinstall the application completely. Make sure you remember your login credentials before deleting. If you use biometric authentication, disable it temporarily and log in with your password first.
Check if your phone number is correctly registered in the system. Sometimes the issue is on the carrier side — contact your mobile provider to verify SMS reception isn't blocked. Try requesting a new code after 5 minutes. As an alternative, switch to push notifications in the app settings or use the hardware token if you have one.
This happens due to session timeouts or poor connection quality. Don't refresh the page multiple times — it may create duplicate payment attempts. Check your account balance first, then verify the recipient details are entered correctly. Wait 10 minutes and check your transaction history before trying again. For online purchases, ensure your card has 3D Secure activated.
Your account might be temporarily locked after multiple failed attempts. Wait 30 minutes before trying again. Verify you're using the correct user ID, not your account number — these are different. Check if Caps Lock is accidentally enabled. If you've recently changed your password, old credentials won't work anymore. Reset your password through the forgot password link if you're still stuck.
High server load during business hours causes delays. Peak times are weekday mornings and lunch breaks. Your transaction is likely processed even if confirmation doesn't appear immediately — check your account statement after 15 minutes. Avoid clicking submit multiple times, as this can create processing queue problems. For urgent transfers, use the mobile app instead of the web portal.
