Had to shut down Mullvad VPN today because it used ~1.5GB of data (of my 2GB plan ๐) over about 30 minutes. No other app is even close to 150MB in the same time period so it can't be that. Why would this occur? I don't trust the app anymore, I was just lucky to have been using my phone while my 2GB warning came up...
[Edit: on wifi the data usage is about 50% Mullvad and 50% all other apps, which seems reasonable, but would speak against for example DAITA (thank you to @ballesterer13 for bringing this up) since on regular data Mullvad has consumed almost 2.6GB and all my other apps combined is ~300MB. Or, why would DAITA consume 1.5GB over thirty minutes rather than just constant extra use -like wifi data shows.]
