Does anyone know if the application (for Windows PC) updates automatically, or if you need to fetch the updates somehow?
The application will tell you if there’s an update available thus if you do not see any notifications within the app you’re good to go!
Click on profile then click on settings. Look at the bottom for which version you have. I got update earlier today btw.
So there is no Profile button on mine. There is a gear icon on the bottom left. The options it shows are general, connection, kill switch, split tunneling, profile, refer a friend, discover other Nord products, that’s it 
Clicking on profile does not show any options to update or check version.
