Snapshot not recognizing API key

Hi there,

Having an issue when setting up the Snapshot plugin - the text says "Great, you already have the WPMU DEV Dashboard plugin installed which will act as the API connection to our cloud storage servers. Next, click Activate Full Backups to enable this service" but the entry box below asks for my API key (with the confirmation button as "activate managed backups" but then doesnt do anything when it's entered. Seems theres some conflict between the WPMU dashboard and the plugin?
