I have noticed that when I plan a flight with Simbrief and bring it into the Sim (MSFS 2020) the flight route shown in the in-game Navigraph flight route is not the same. This became noticeable a few miles into the flights when I noticed the Simlink pink icon showing the plane location was off course by many miles - according to what was shown on the Navigraph chart. When I checked what was uploaded into the Sim it was what Simbrief suggested, but it does not show correctly in Navigraph - meaning it’s not the same data.
A flight that I did yesterday from KPHX to KLAX was my last example. I flew the PMDG 737-800. Airac is the latest update with my premium account through Navigragh.
This is just one example, but there have been many of these lately on various planes. Am I doing something wrong? I am making the assumption that the date in Simbrief and the data that was loaded onto the game by Navigraph should be the same data.
