I turned on the Display stretched in the overlays in the UV Edit screen. Instead of getting blue quads, I got some funky colors and some blue-ish quads. I continued and Auto Aligned a quad into a square and tried to apply the Follow Active Quad. Nothing happened. Is this a 4.0.2 thing or did my Blender version drop some acid? (For whatever reason now I can submit a photo?). Will try again after posting this.
Sorry if i reopen the case, was having same issue with version 4.1.0. After long try and search what worked for me was selecting the active face and then selecting linked. Wonderfully everything straightened up.
