Since Microsoft Health updated, I have had numerous moments when my cell phone (Lumia Icon) used enormous amounts of data. 1 GB at a time, a couple times per day. Sometimes in the middle of the night, when I'm sleeping. Has anyone else noticed something similar? I don't have a way to track which apps are using data, so I'm trying to verify whether it's Microsoft Health. I haven't installed any other apps, and the first data explosion happened on 2/23, which is when Health updated.
