Hi @Polarising – just to clarify, do you have a .devcontainer or devcontainer folder? As per the spec, the folder needs to be called .devcontainer.
Nested files do show up for me when using “Switch Container”. We do require that the .devcontainer folder is mounted within the container.
Additionally, not sure if its an issue on my end, but the SSH-Key forwarding does not seem to work like in VSCode, as my same config that used to work with the previous Extensions now does not work anymore.
Thanks for raising this. What platform are you on, and are you using Docker over SSH, or are you running Docker locally?
