I've recently started to use NordVPN on smartphone as I need to spend a lot of time in public networks.
However, it is only 5th August and I have already got a data warning that I have used 2GB of mobile data.
Which makes me think that NordVPN does not change the "carrier" network automatically, when I switch from LTE (4G) to some WiFi (office or home).
I've contacted NordVPN support team, they told me that all traffic is accounted for an actual app (e. g., Firefox) and NordVPN. The problem is that the mobile plan provider somehow adds these two traffics. I use an Android phone.
How to solve this problem? Thank you!
