If I go to
Settings -> Apps & notifications -> Instagram (or some other app)
and turn notifications off for that app, does that stop data usage on my data plan? I ask because the message, when you turn notifications off for an app, is
At your request, Android is blocking this app's notifications from
appearing on this device
which would seem to imply that the Android OS will receive the notification, and swallow it up at the OS level. Which would imply that the phone does receive the notification from the network, thus some data usage would occur against your data plan.
So does blocking notifications stop data usage, or not?
