If a profile’s displayed amount does not match other sources.

A profile counts the total amount of data moved by applications while it is active. While in most cases this matches a given connection, there are some cases where TripMode cannot ensure fine grained attribution:

In all cases, it is important to remember that a profile is a set of blocked and allowed applications with optionally an alloted traffic amount. In automatic mode one is created and named after a primary connection when it is used but this does not mean that it is exclusively associated with it. Specific connectivity or manual selection can alter the traffic seen by a given profile.
