Sometimes the browser does not update the extension automatically. You may want to manually check for extension updates first. The latest version usually solves some problems.

It will be of great help if the description is detailed. For example, which function was not working properly, on which page the issue was found, whether it appeared every time or occasionally, etc.

Any contact method is fine. I‘ve graduated and no longer have access to most pages, so I need to contact you for more details.
