Unfortunately this is a setting I may have to remove from the plugin, because the major calendar apps (Google Calendar, Office 365) have stopped using the proper URL field in their .ics output, and instead put links directly in the descriptions. As the plugin currently works, it only make the titles clickable links if the proper URL field is used.
One possible change I could make is to enhance the logic so if the URL field is not used, it would instead scrape the description for the presence of a URL, and use that as the link for the title. I’ll investigate the feasibility of implementing this change in the next update.
