Hi, I’ve found a solution (I’m on Windows 11) :
First step (Perhaps it’s not necessary and you can go directly to the second step)
- Open the Microsoft Store app on your computer.
- In the bottom left corner of the Microsoft Store, click on the library icon and make sure that there is no update missing
- Click on your profile icon in the top right corner of the screen.
- Under your email address, click on "Sign out".
- Reboot the computer
- Open the Microsoft Store app.
- Click on the icon in the top right corner, then click on Sign in.
Second step
- Open MSFS, go to Options > General > Data
- Toggle Online Functionality, Bing Data World Graphics, Photogrammetry, Live Real-World Air Traffic, Live Weather and Multiplayer "OFF"
- Click on Apply & Save
- Toggle Online Functionality, Bing Data World Graphics, Photogrammetry, Live Real-World Air Traffic, Live Weather and Multiplayer “**ON” again.
- Click on Apply & Save
And then everything works perfectly, market place and manager content was there !
