Hey there, thanks for reaching out and welcome to the Streamlit community! The error “You do not have access to this app or it does not exist” on Streamlit Community Cloud usually means there’s a mismatch between your Streamlit account and your GitHub repo permissions, or the app’s GitHub coordinates (repo name, branch, or entrypoint file) have changed. It can also happen if your app is set to private, your GitHub account isn’t properly linked, or you’re signed in with a different email than the one associated with your GitHub account.
