When you run a profile in the cloud, the browser is not running on your computer - it runs on a remote server. Because of this, downloading and uploading files works a bit differently than in a local browser. Files go through an intermediate step via the cloud container.
Downloading a file to your computer
Download the file from the website as you normally would. The file will be saved to the cloud container, not your local machine
Click the Files icon in the bottom-left corner of the cloud browser window
Click the ↓ button next to the file name
A file explorer window will open on your local computer. Choose a folder and save the file
Uploading a file to a website
Click the Files icon in the bottom-left corner of the cloud browser window
Choose Click or drag files here and select the file from your local computer. The file will be uploaded to the cloud container
On the target website, click the upload button
A file explorer on the remote container will open. Go to the Downloads folder, select the file you uploaded, and click Open
