Double-check that your Publishable Key is correct and starts with pk_. Make sure you are using the key from the correct environment (development vs production).

Check spam folders first. In Clerk dashboard, verify your email settings and consider adding a custom sending domain for better deliverability.
Make sure the page is correctly marked as protected in your JustCopy project settings. Clear your browser cache and try in incognito mode.
Use the Clerk dashboard Customization section to adjust colors, fonts, and layout. Changes apply automatically to your JustCopy site.
Check your redirect URLs in Clerk dashboard settings. Ensure the URLs match your JustCopy domain exactly, including http vs https.
