My App update was Rejected and Apple has sent me a message :
Thank you for submitting your app for review.
We need additional time to evaluate your submission and Apple Developer Program account. Your submission status will appear as "Rejected" in App Store Connect while we investigate. However, we do not require a revised binary or additional information from you at this time.

Has anyone else had the same experience? How can I solve this problem ?
Yeah, I have met this message several times. Typically this means your review may be delayed for more days. Last time we waited for 7 days, and on the 8th day, we wrote a mail asking what’s the review progress. Then the apple review team replied and continued its review.
So I suggest you wait patiently and reduce the submission frequency. And better not use private APIs next time.
