Before your app is made available in the App Store it will go through a review process.
The review process is performed by a reviewer that works for Apple, and it consists of a series of tests and checks to make sure that your app works as intended and follows all the guidelines from Apple.
You can find all the review guidelines from Apple, here: https://developer.apple.com/app-store/review/guidelines/
The review process usually takes 3 business days to be completed, but it can take more.
You can find all the details provided by Apple about the review process here: https://developer.apple.com/app-store/review/
If your app gets rejected by Apple, more details will be provided in the Resolution Center, accessible via your App Store Connect account. In most cases no actions will be required on your end, MobiLoud will take care of reviewing and performing the necessary adjustments to get your app approved, but if anything is needed from you, we will let you know.
