I have problem with my app, it has very high network activity. I have built standalone versions for iOS and Android and released them in Appstore/Play.
When starting the app it consumes around 13Mb from network. Sure we have some API calls to remote systems but expected data is < 10kb.
We have a video (6Mb) that is shown at startup, after bootstrap, but that video is bundled with the app. Switching to airplane mode, the video is never shown.
Also we have one user that has reported the app has consumed 770Mb in background for 2 days. According to him he has started the app but never logged in. To our knowledge we can not understand the high data consumption in background.
So the general question is how can I monitor the network activity to see and understand the data consumption.
Two more specific questions:
-why is not the video loaded when in airplane mode?
-what causes the app to consume high volume data in background?
