Hello there,
I have the same issue with my app https://lambard-ml-team-madgui.streamlit.app/
I will be happy to here some news about this issue.
Also I have another issue that is more “dangerous” for me, it is that when a user leave the app without clearing it (reset the session_state) then another user can have access to it. Or when there is two user on the app there is a conflict.
I saw on Where does the data go when using file_uploader? When does it get deleted? - #18 by Jason_K that I may be due to st.cache but I have to check to confirm. It is still a problem that it doesn’t work like in local where it opens a localhost:8501 and if you open a new one it opens localhost:8502 with 0 interaction between both of them.
