I am getting frustrated with my xfinity data usage over the monthly limit and so I installed glasswire in a computer on my home wifi network yesterday. I was trying to find out which device(s) on my home network are using most of my data. How come for a given period of time, glasswire reports less than 1 GB of data used while xfinity reports 60 GB of data usage? How accurate is the glasswire measurement vs the xfinity measurement? How come is there such a big difference? Thank you.
