The Session Frontend Screen Comparison tool does not appear to be showing and screenshots taken from the Editor.
Results: No screenshots are showing up in the Screen Comparison window. When doing this in 4.21 the screenshots are not saved at all.
Expected: The Ground Truth, Delta, and Incoming screenshots should appear after the second test.
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-68198 in the post.
