What are the plans for replacing the flash components within Performance Center? Adobe is deprecating Flash in 2020, and Chromium is targeting disablement in July 2019, and removal by December 2020.
There is work going on to remove Flash that continues. It's not removed in r3.7 and is still used in that release.
Hopefully the next release, or one soon after that, will have it pulled from the code without impacts to existing functionality.
There is an Idea posted here about it if you haven't seen it yet.
