Starbucks passion fruit iced tea lemonade

The teavana iced passion tango tea with lemonade says it’s kosher on the kosherStarbucks site ( certified olk or lko)
I went there today and the passion fruit is no longer teavana Bc starbucks bought them and the Starbucks passion fruit box didn’t have any certification.
Is this drink still kosher ?
And if yes, is lko a good hashgacha ?

Kosher. LKO is a good hechsher

is the mango dragonfruit kosher?

Problematic due to the white grape juice in the ingredients
