My error log is flooded with warnings that look like the following. This is a simple site without load balancing on a server with other sites hosted on IIS. After searching I thought the problem was that we are using "app.UseSession()" in our Startup.cs without providing a unique name to each site, but I've added a Cookie.Name to the "services.AddSession" and we are still seeing tons of these warnings every day. Is there a correct way to setup session for Umbraco 10? Is this not session related? Do I need a machine key in my web.config even if we're not load balancing?
