If the page shows only {} you are not signed in. Sign in to ChatGPT first, then reload that tab.
Good to know
- How long does it take?
- Most orders finish within a few minutes. Busy periods can take longer; the page keeps updating on its own.
- Is my session safe?
- It travels over HTTPS and is used only to apply your subscription. Sign out and back in after activation to refresh your credentials.
- What if it asks for verification?
- Some orders need a short security check. A button appears on the status screen. Open it, finish the check, then return.
- Can I close the page?
- Yes. Come back and use the Track tab with the same code to pick up where you left off.
