I tried to update the game today after maintenance, but it keeps giving me a pop up saying "app not installed" I tried deleting QooApp and TouRabu app to try again, but it still doesn't work. I can't even install the app, let alone update. I have 1.6GB available. Does anyone know why or have the same problem?
