Same problem. All our apps (IDs: 6756160582, 6756997290, 6758690019) have been in "Waiting for Review" for more than one month, and we have received no specific response explaining why it is taking so long. We hope the developer team can support us or elaborate on what we can adjust to speed up the review process.
