Hey,
i have recently noticed that an app was on a lower version on the App Store than on my phone. The company advertised with new features on their social media, and the features also were on my phone, added new, and the version inside the app changed, but the app in the App Store did not, there was no new update.
I am supposing that they found a way to update the app directly, without having to send it to apple first.
Is this against the guidelines, or is there a way to do this kind of stuff without any risk? Is it is against the guidelines, can someone provide me with the corresponding paragraph? because I couldn't find anything that would apply directly.
