Known Issue: Sign-Up Page Redirects to Sign-In

Affects: v1.0.41
Status: Identified — fix pending
Severity: Medium — external links and query parameters are broken

What Is Happening

The sign-up route (/sign-up) currently contains no registration UI. Instead, src/app/sign-up/[[...sign-up]]/page.tsx immediately redirects every visitor to /sign-in without displaying a message or providing any user feedback.

This means:

• Anyone who clicks a "Sign up" link in a marketing email, advertisement, or partner referral page lands on the sign-in screen with no explanation.
• Any query parameters attached to the original URL — including ?callbackUrl, campaign tracking parameters, and referral codes — are silently discarded by the redirect.

Who Is Affected

• New users following sign-up links from external sources.
• Marketing and growth teams whose campaign attribution relies on query parameters surviving the landing page.
• Integrations and partner systems that append a callbackUrl to the sign-up link to return users to a specific destination after authentication.

Workarounds

While the fix is being implemented, the following workarounds are recommended:

For users

Navigate directly to /sign-in to access the authentication page. Sign-in and account creation are currently served from the same page.

For teams managing external links

Update all /sign-up URLs in emails, ads, and partner sites to point to /sign-in instead. If you need to preserve a callbackUrl, append it directly to the sign-in URL:

https://your-sidekick-domain.com/sign-in?callbackUrl=%2Fdashboard

Planned Fix

The engineering team is evaluating two approaches:

Option A — Implement a dedicated sign-up page

Build out the /sign-up route with a full registration UI that mirrors the sign-in page style, using OAuth buttons labeled "Create account".

Option B — Redirect with query parameter preservation

If sign-up is intentionally unified with sign-in, update the redirect to forward all query parameters so that callbackUrl and referral data are not lost:

// src/app/sign-up/[[...sign-up]]/page.tsx
redirect(`/sign-in?${searchParams.toString()}`);

Option A is the recommended long-term approach as it provides a clear onboarding experience for new users.

Summary of Impact

Scenario	Current Behaviour	Expected Behaviour
User visits /sign-up	Silently redirected to /sign-in	Shown a sign-up / create account form
User visits /sign-up?callbackUrl=/dashboard	Redirected to /sign-in, callbackUrl lost	Redirected with callbackUrl preserved
User visits /sign-up?ref=partner42	Referral parameter dropped	Referral parameter forwarded
Marketing email links to /sign-up	Lands on sign-in page, no context	Lands on sign-up page or contextual sign-in
