It seems like you're experiencing a recurring issue with Opera's update process, where despite restarting the browser as prompted, the notification for a new version persists. To address this, you could try a manual update by downloading and installing the latest version of Opera directly from their official website. Additionally, clearing your browser's cache and cookies might help eliminate any interference caused by cached data or cookies. It's also worth checking for any conflicting software on your computer that could be hindering Opera's update process, and temporarily disabling such programs, including antivirus or firewall software, to see if it resolves the issue. If these steps don't work, you may need to consider uninstalling and reinstalling Opera to ensure a clean installation without any lingering issues from previous versions. If the problem persists, reaching out to Opera's support team for further assistance would be advisable, as they can provide tailored troubleshooting steps or insights specific to your situation.
