A. Ensure that your internet connection is stable. Switch between Wi-Fi and mobile data to see if the issue persists. If using Wi-Fi, try restarting your router. Additionally, clear the app cache by going to Settings > Apps > YONO SBI > Storage > Clear Cache.
B. Check for app updates in the Google Play Store. An outdated app may have bugs that affect transaction smoothness. If an update is available, install it and restart the app.
