What product does my customer have?

We currently have two different products: Our old Mac-only licenses and Workspaces subscriptions (Standard or Business). Mac-only licenses are the ones that have a license key number, starting with SK3. Workspace subscriptions are registered using the customer’s email address + password combination. The customer can check what licensing system they’re under by accessing the following menu on the mac-app: Sketch > Settings > Account. If it shows “Unlink device”, they are registered with a Mac-only license; In case it appears “Sign out”, that means they’re registered using a Workspace subscription
