         #### Prerequisites before submitting an issue!
         - Read the issue reporting section in the **[contributing guidelines](https://github.com/qbittorrent/qBittorrent/blob/master/CONTRIBUTING.md)**, to know how to submit a good bug report with the required information.
         - Verify that the issue is not fixed and is reproducible in the **[latest official qBittorrent version](https://www.qbittorrent.org/download.php).**
-        - (Optional, but recommended) Verify that the issue is not fixed and is reproducible in the latest CI (**[macOS](https://github.com/qbittorrent/qBittorrent/actions/workflows/ci_macos.yaml?query=branch%3Amaster+event%3Apush)** / **[Ubuntu](https://github.com/qbittorrent/qBittorrent/actions/workflows/ci_ubuntu.yaml?query=branch%3Amaster+event%3Apush)** / **[Windows](https://github.com/qbittorrent/qBittorrent/actions/workflows/ci_windows.yaml?query=branch%3Amaster+event%3Apush)**) builds.

         - Check the **[frequent/common issues list](https://github.com/qbittorrent/qBittorrent/projects/2)** and perform a **[search of the issue tracker (including closed ones)](https://github.com/qbittorrent/qBittorrent/issues)** to avoid posting a duplicate.
         - Make sure this is not a support request or question, both of which are better suited for either the **[discussions section](https://github.com/qbittorrent/qBittorrent/discussions)**, **[forum](https://qbforums.shiki.hu/)**, or **[subreddit](https://www.reddit.com/r/qBittorrent/)**.
         - Verify that the **[wiki](https://github.com/qbittorrent/qBittorrent/wiki)** did not contain a suitable solution either.
