Android App is not working when I connect with Wifi but it runs when I connect with Mobile network.

[Android Central Question]

Hello, I had developed an application in both iOS and Android. When I run it in my Wifi, the android application won't run properly and show some lagging issues while when I run iOS application it runs instantly. Both applications runs when I connect my device with the Mobile network. Can you please help me out?
We had also tried to run the application by using different Wifi network but the same problem we faced.

Did you develop the app (figure out what it had to do at each stage, then code it - into Swift for iOS and Java.Kotlin for Android? Or did you run one of those "app making apps" that takes a "sort of app" and gives you code for both? If you did that, the app making app isn't accessing the internet properly. Either email the developer and ask them to fix it, or go through the source code (if you get it) for the Android version, find out where it's accessing the internet, and refactor that to do it properly. (You never use the individual connection [wlan0 or whatever the mobile data connection is named], you use the generic "internet" connection.)
