You're not doing anything wrong, @anne103. From what you've described, this behavior is likely related to your browser, such as cached files or compatibility issues. I recommend trying some browser troubleshooting steps to address this.
Let’s start by clearing your browser’s cache to remove any stored files that might be affecting performance. You can also use another supported browser, as it offers a fresh setup and can help rule out any browser-specific settings or conflicts.
