Hello,
We’ve gotten our projects rejected (seemingly) at random, and this is always what iOS gives us as reasoning (see image).
We personally have no reference to any attribute or API in our projects using something called ‘credentials’ and again, this seems to occur at random… if we re-submit there’s a chance the app will go through and be passed, but it’s annoying to have to rely on chance with this. We are using build 2952 of Corona SDK. We are also using Fuse ads, so we have that set up in build settings.
