But then you're lying. Why not add the comment "no tarot function" without reference to whether it existed in the past? A bit confusing because it's a trivial and seemingly unrelated statement but at least then you wouldn't be lying.
Why not just lie? The white lie is the most expedient thing to get the results you want, which is getting the app into the app store. It's not a slippery slope into a total moral decay of you as a human being. If a friend is hiding from an abusive partner, and that partner asks where your friend is, telling the truth would put your friend in danger, so lying is an important skill to have. The lie in this case gets past a pointless requirement.
You can just add one and then remove it. That way you're not lying. And also it doesn't sound like you're disagreeing with them so you sound like a problem.

Why not say “app now has no tarot function” which can be read as implying that it used to but doesn’t actually say that.
