Reasons for an IQ Store app to be rejected after review

Hello everyone,

I uploaded a new widget I made on the Connect IQ Store 2 days ago, and I just saw it has been rejected. However, I can't find the reasons for this and even after reading again the "App Review Guidelines" I can't figure out what was wrong about my widget. FYI, it's a widget which generates QR codes from the watch to control GoPro cameras.

Anyone knows where can I find more information about why my app was rejected ?

Have a nice day!
