Nature's Path Mesa Sunrise- has it always been 26 oz bag?

I've been buying Nature's Path cereals a lot lately-- in particular Mesa Sunrise (my favorite) and Heritage Flakes. Yesterday I picked up a bag of each at the store, and suddenly noticed that the Mesa Sunrise felt "less full". Then I noticed that it is in a 26.something oz bag while the Heritage Flakes was 32 oz, and they're the same price.

I can't find anything on the internet about a downsize of Mesa Sunrise bags-- has it always been 26oz and I never noticed? I feel like I'm going slightly crazy.
