For fun I would check it at night before Bed and it would say something like 474GB. I wake up and it says 475. Then a few hours later it's 490. I'm the only one here doing anything. I have the TV on Fox 2, so I'm not sure that's eating up internet, its through the cable box. I checked our laptop and tablet, both have no apps open. I'm not downloading anything heavy for work. Just emails and such. I'm sure there's a delay in the numbers. I'm not a conspiracy guy but still..... in the summer of 2021 we went over but I discovered it was due to my special needs son binging on the Muppets on Disney Plus on the ipad. So I downloaded all of it, problem solved. Our usage went down considerably ever since.
