Photo AI 2 Subject Detection flaw and Sharpening noise artifact

I didn’t use Photo AI 1 much (a Sharpen AI fan) and just got 2.1.2. Very disappointed with sharpening and subject detection in Photo AI 2. Can’t identify a flower (included half a zinnia flower plus a leaf). Sharpening the whole image (with subject detection off ) created a grainy look that wasn’t in the original - too much local contrast instead of true sharpening?? Anyone having similar experiences?
