I try to applicate the download button on my streamlit application.
But the following error occured.

Hi @pyutaro

Where have you deployed your app? If it’s Streamlit in Snowflake, st.download_button is not supported.

Hi, @snehankekre

Thank you for replying!

I understand we can’t use the st.download_button.
We hope it will eventually be implemented!
