Froot Loops Kosher?

Hello, I’m in the process of converting and interested in keeping kosher, this is quite difficult in australia so i downloaded the “kosher australia” app to help. Problem is I searched up froot loops to which it is stamped “not kosher”. I googled why froot loops aren’t kosher out of curiosity because i assumed they would be- I can only find articles online that say they ARE kosher. So i’m confused? I’ll assume they are kosher but in that case why is the app wrong? is this something i can actually use and trust? Any one else who uses the app or has an idea why it could be wrong would be very helpful.
