Poppi Differences?

I started drinking poppi recently and I love it and it’s a great fizzy drink with “health benefits”

However, I drank one last night tasted all good then I drank one this morning that I recently bought and it tasted different. I bought the new ones from Kroger and it tasted sweeter, less fizzy and I honestly thought somehow it went bad. I grabbed an older one for a comparison and saw the ingredient change and can change.

I got my Whole Foods poppi early January and bought the Kroger one yesterday (1/2). Is anyone aware of this or maybe they have 2 different recipes? The Kroger one was cheaper for a 4 pack. Let me know!
