Hi, this is a normal behavior due to how docker works. Mounted folders are only mounted in the container - the terminal is in a separate container (of the host). However, if you install portainer, you can have a console inside the container and see the mounted folder.
That’s why each of my addon has a separate mount option for smb drives.
@adamoutler has another solution : an addon that can execute the mount code at addon startup : see here ✔️🏃Run On Startup.d
So if you don’t log in the container with ssh or portainer, you need to trust it to work and go see in your smb disk files appearing after download.
