Hey @wang_dashi,

Welcome to the streamlit community!! :tada::partying_face::tada::partying_face:

That’s great! Glad you got it fixed up! Can you post the line of code you changed so future users who have this question can see the code you used to fix it!

Happy Streamlit-ing!

sure,the code is:
st.sidebar.header(‘huawei apps store:’)
st.sidebar.subheader(‘1.please chose which app you want to operate’)
