Reproducible Code Example

No response

Steps To Reproduce

Simple repro on Streamlit’s own demo.

1. Open anonymous browser
2. Go to https://multipage-v2-preview.streamlit.app/page2 (Don’t visit the main url first).

Expected Behavior

Expected behavior was that entrypoint with st.navigation would be loaded first, but that doesn’t seem to be happening. This renders new navigation unusable for any app app requiring a deeplink for first time visitors.

Current Behavior

No response

Is this a regression?

• [ ] Yes, this used to work in a previous version.

Debug info

• Streamlit version: 1.39
• Python version: 3.10
• Operating System: Linux
• Browser: Arc and Chrome

@srail Thanks for reporting this issue. I can't reproduce it with a simple app using st.navigation and the latest version of Streamlit. The issue in multipage-v2-preview might be related with the login/logout logic used in the example. Can you reproduce it with a simple app using st.navigation?
