A checkout that forgets Pro after signing back in

Paying worked and the account showed Pro. After signing out and back in, “Pro” was not on the page. After the fix, the same steps did what the sentence says.

The sentence it was given

A customer can upgrade to Pro, receive access immediately, and retain Pro after signing out and signing back in.

Every step the browser took

One journey of eleven planned steps. The run after the fix took the same steps.

What it found

Step 11 of 11

Expected: Plan shows “Pro”
Observed: “Pro” was not on the page

The Lumen Notes account page after signing back in, before the fix: Current plan shows Free.

The repair prompt it wrote

It is written for the coding agent that built the app: what was expected, what happened instead, and how to see it again.

Repair prompt

A check of Lumen Notes failed on https://broken-checkout.vercel.app. It ran in a real browser against the deployed app, from the outside, as a user would.

WHAT WAS BEING CHECKED
Plan shows “Pro”

WHAT HAPPENED INSTEAD
“Pro” was not on the page

HOW TO REPRODUCE
1. Open /pricing.html
2. Click “Get Pro”
3. Click “Pay”
4. Open /account.html
5. Check Plan shows “Pro”
6. Start a fresh browser session
7. Open /signin.html
8. Sign in as the test customer
9. Confirm the session is signed in
10. Open /account.html
11. Check Plan shows “Pro”

WHERE IT FAILED
Step 11 (Check Plan shows “Pro”) is where it stopped.

WHAT I NEED
This was observed from outside the app, so I know the symptom and not the cause. You have the source. Find why this happens, fix the underlying cause rather than the symptom, and tell me what you changed and why. If reproducing it needs something I have not given you, say what.

The run after the fix

It took the same eleven planned steps as the run before the fix, and none of them found a problem.

Outcome: Did what the sentence says
Run ID: 588c48f7
Recorded: 2026-07-22
Duration: 9.0 s

The same account page after the fix: Current plan shows Pro.

What this shows

Paying worked and the account showed Pro, so it looked done. After signing out and back in, the plan was Free. A check of the payment step alone would have passed.
