double click on the radio button when switch back & forth between pages

I think the issue is with the app_state assignment.

This is what I have tested on my own multi-page app,

Instead of st.experimental_set_query_params(**app_state), I switched to st.experimental_set_query_params(**st.session_state.to_dict())

This is a known issue related to upraneelnihar/streamlit-multiapps#2. The reason for using st.experimental_set_query_params(**app_state) is to create direct link to preselected sidebar menu, such as the link below. Changing it to t.experimental_set_query_params(**st.session_state.to_dict()) would lose the direct link functionality.

Ah, I see. Yup, the same thing happening on my end. Let me poke around ;)

Not quite sure what happened... But this is how I get it to work for both the "direct link visit" issue and avoid the "double click on the radio button to switch back and forth" issue.

        pressed = st.session_state.radio 
        app_state["page"] = pressed

        st.experimental_set_query_params(**st.session_state.to_dict())
        functions[titles.index(title)]()

It seems that app_state["page"] = st.session_state.radio is the culprit? Because when I have the following:

        app_state["page"] = st.session_state.radio
        st.experimental_set_query_params(**app_state)

Direct visit works, but I have to click on the radio button twice in order to switch to a separate page. It almost as if app_state["page"] = st.session_state.radio assignment ignored the first time a radio button is pressed.

Frankly, a bit confused...
