***Not a copy paste letter*** Hello, I can fix your app right now, No needs to pay first, send me the source code. I will fix within some hours from now, And then you will check. And you will pay if only works. I know why app crashes in Android 9 as there is new network security policy. I need to check it during API call. I can do it as I have done this upgrade in many existing projects for my clients so far. So i can overcome it, and fix the ANR right now. I will also give a complete revision of the app, and will check on Android 4.4 to Android 9.0 for insuring the fix! I can start now, Waiting for your message! Thanks Mujahid
