The frameless output does not function correctly in terms of clicking on TOC topics or really anything else. It works fine for both Chrome and Firefox. Is there anyway to change the output to work for IE or Edge?
The frameless output works in the modern version of Edge but you will have issues with IE. That's why Microsoft no longer support it and recommend Edge. I assume you mean the recent versions of Edge that are Chrome based. If you do mean the older version that is no longer available, frameless will not work on that.
Both 2019 and 2020 use HTML5 and CSS3 which are poorly supported by IE and the old version of Edge.
