In What Sense is Frege's (Statement of the) Puzzle 'Problematic'?

I take issue with Glezakos’s explanation of why Frege’s puzzle is un-puzzling. On her view, Frege’s statement – how can sentences of the form a=a and a=b, if true, differ in cognitive value if they express the same semantic content/are made true by the same object’s self-identity? – should not be considered any puzzling either because it is on the whole circular, or because, neutrally stated, it cannot even be set up. I argue against this that if, as she takes it, Frege’s statement is “problematic” it is not for the reasons she gives, but because it rests upon a couple of questionable assumptions: i) there is no ambiguity as to which aspect of the sign (in its relation to the referent) is relevant to a neutral statement of the puzzle ii) it is of the (sentence) forms themselves one may sensibly say they differ in cognitive value.
