Without making a purchase, you can view an app demo of your website using the drag&drop FluxBuilder App Builder. Afterward, you can build the test APK for free.
Please do not test the App's features on the simulator of FluxBuilder because of limitation of Flutter framework.
Non-work features are NORMALLY because they require additional configuration (e.g. Map, Social Login, Push Notifications, Dynamic Link, Realtime chat, etc.). So if they don’t work on your App from Test APK or Test iOS, it is PROPERLY because they need to configure more.
