I keep getting traffic from my phones from what's app and it is not installed on one of the phones. I have it installed on my phone and get like 300 kb/month but my wife's is getting 2 or 3 mb per month. She says she doesn't have it installed. So I've read that the software isn't that great allocating traffic. Is it possible my traffic is being misattributed to her phone somehow or are there questions I need to ask of her?
I have an Asus RT-AX82U. I'm using the built in software from the router with firmware 220.127.116.11.386_49674. I'm seeing this traffic on the traffic analyzer.
