Login works (Firebase auth succeeds) but app does not navigate after login until page refresh (Web)

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

We are experiencing an issue with the login flow in a FlutterFlow web app.

After clicking the Log In button:

Firebase authentication succeeds (user appears in Firebase Auth),
the user session is correctly established,
however, the app does not navigate to the next page (neither via manual navigation nor automatic redirect).

Only after manually refreshing the page, the app correctly recognizes the authenticated state and loads the proper screen.

##Actual behavior

Login succeeds,
subsequent actions (e.g. Snackbar) execute,
but navigation does not happen,
app stays on login screen,
after browser refresh → user is correctly redirected.

Expected Behavior

After successful login, the app should immediately navigate to the target page (either via manual Navigate action or via Logged In Page redirect).

Steps to Reproduce

1. Enter login/pass and click on Login.

What we tested

We performed extensive debugging to isolate the issue:

1. Button & action flow
   Verified button click works (Snackbar displays correctly)
   Confirmed action chain executes after Log In
   Tested:
   Navigate To
   Navigate Replace
   Rebuild Page
   None of them trigger navigation
2. Removed all complexity from login screen
   Created a completely new, minimal login page:
   email + password fields
   single button with:
   Log In
   Navigate
   Same issue persists
3. Tested navigation independently
   Added test button with only Navigate To → works correctly
   → navigation system itself is functional
4. Tested with minimal destination page
   Created a completely empty test page (no queries, no logic)
   Navigation still does not happen after login
5. Tested with and without manual navigation
   Variant A:
   only Log In
   using Logged In Page in App Settings
   Variant B:
   disabled global redirect
   manual navigation after login
   Neither works
6. Removed all Page Load logic
   Removed On Page Load actions (including App State updates)
   No change
7. Removed NavBar / custom navigation dependencies
   Tested navigation to:
   NavBar page
   non-NavBar page
   Same behavior
8. Verified issue is not UI-related
   Other buttons on the same screen (page switching, interactions) work correctly
   Issue is specific to login flow
9. Tested across environments
   FlutterFlow Test Mode
   Deployed web app
   Different browsers
   Incognito mode
   → Issue persists everywhere

Additional observations

Firebase Auth clearly succeeds (user is created / logged in)
App state updates correctly (user ID available)
Behavior suggests routing is not triggered or is overridden after auth state change
After refresh, routing works correctly → indicates delayed or blocked state sync

Environment

Environment

Platform: Web (issue occurs in Test Mode and in deployed version)
Browsers tested: multiple (including incognito)
Same behavior across all environments
