I don't know, it sounds too inconsistent to be real. Chie has always been an outspoken supporter of nH and SS. Why would she be disappointed in the fulfillment of her OTP? Unless her grief pertained to another issue concerning the movie like the abnegation of Sakura's heroine role (but Chie isn't above criticising Sakura's charcter herself), broken assurances to resolve to all remaining questions like Kaguya's origins, or something else that she's not explaining.
This about NH was never confirmed.
I believe she is sakura-centric, she made comments about NS in the past, I think she was not bothered by it, even if she prefers SS
