Open DeepChamp AI
If DeepChamp AI is already installed, this page opens it directly to the login handoff so you can use the same purchase email.
Magic link handoff
Your backup magic link is still valid. Download DeepChamp AI first, then use the same purchase email. If the app is already installed, opening the sign-in link from Apple Mail, Gmail, or Safari gives Firebase the best chance to hand you directly into the app-backed account session.
