Hey, thanks for reaching out! Normally, Streamlit Community Cloud apps update almost instantly when you push changes to your GitHub repo. If your app isn’t reflecting updates—even after a reboot—this could be due to a temporary sync issue, a problem with the GitHub connection, or a rare bug on Streamlit’s side. This has happened to other users before, and sometimes the issue resolves itself after a short while, but not always automatically according to Manage your app - Streamlit Docs and community reports.
Recommended steps:
- Disconnect your GitHub account from Streamlit Community Cloud (via Settings), then reconnect it to refresh permissions and sync (source).
- If that doesn’t work, try deleting and redeploying the app—this often resolves persistent sync issues (source).
- Check your app logs for errors (Manage app > Cloud logs) to see if there are any clues (source).
If you can, please share a minimum reproducible example or your repo link so the community can help debug! And if anyone else has insights, please jump in and share your experience.
