Change in Cafe Mocha, or Bad Batch

I’ve been drinking Coffeist (Cafe Mocha) twice a day, every day for 4 years, and recently got a few boxes that expire May 2021. The flavor of these two boxes has been completely different, I can barely drink them. Instead of a calm coffee and cream taste, they have a fake chocolate and artificial sugar taste. Did they change the flavor of Coffeist (for the worse) or did I get a bad batch? Has anyone else had a problem with the latest Coffeist?
