Description

The MLP design selection screen should be enhanced adding the ability to select between mobile(default) and desktop thumbnails. The design might be similar with #2978

The MLP API call should be enhanced to provide the mobile/tablet thumbnail urls.

Goals

• The MLP design selection screen displays a thumbnail mode icon.
• When the icon is pressed a popup appears with “Desktop”, “Tablet”, “Phone”options.
• The “Default” “Phone” option shows the mobile thumbnails and loads on first launch.
• The “Tablet” option switches to a tablet thumbnail mode.
• The “Desktop” option switches to a desktop thumbnail mode.
• Analytics events should be emitted to:
  • Track the user tap on the mode button for the design and preview screens
  • Track the mode change for the design and preview screens
  • Track the default mode used in the user session
