I think it is pretty easy for me. Login in Mesh App. I think it automatically sync all folders that are already in the cloud. At least that's what I remembered, the folder from cloud just appears on my desktop automatically.
But yeah, there is many quirkiness with Mesh. Like it is hard to access the cloud via browser. You need to get to some strange place called "Device" and you have to set mobile browser to "desktop mode" to access the Mesh without installing the app.
