Yeah !!! Sorry for my enthusiasm but someone else finally have the same issue as I do.
I have an open case regarding this since months (but I am on 8204) and no resolution yet.
You will probably have the same issue with Edge or any other "modern" browser.
The module exist but cannot be accessed.
Do you pass by IIS to secure your system ?
If you bypass IIS and run directly without security, it will probably work.
It seems to be an issue between IIS and Tomcat.
I suggest that you open a case a mention case 200121110.
Maybe it will help both of us to resolve this.
