Add backer to profile when pre-order of new device.

Your lab card only shows products that have shipped—pre-orders don't pull in until they leave the warehouse because the sync matches tracking numbers to your email. Once the Harlo Lotto ships, it'll show up automatically after you hit "Sync my orders" on the card. The system waits for fulfillment so the hashrate and stats match real hardware on your bench. If you want to see your order status before it ships, check the store's order history page instead—Labs is for tracking live miners. Common mistake: expecting a miner to appear in Labs the day you order it instead of the day it ships.
