We received the same email today.
Ideas/suspicions:
If you use RevenueCat, you know that they had a major two hour long outage on Friday February 10th. Any customers who made purchases during that period were unable to unlock content after paying. The issue was resolved, but any affected customers will need to manually Restore Purchases. Perhaps Apple's systems detected this as a form of "payment fraud".
A nefarious competitor is attempting sabotage your apps by buying fake reviews. Would be easy to detect if you notice an unusually high amount of new reviews for your apps. If so, disclose this to Apple immediately.
An unusual spike in downloads may have triggered this.
Other:
We investigated the email headers, and it looks like a legitimate email from Apple. But we can't be certain it's not phising, so do not share any sensitive information.
Besides the "Please address this issue promptly", there isn't much of a call to action. We reviewed our apps, analytics, reviews, etc and responded with our findings to show everything is in order. I'm not sure what going to happen next, but others have said Apple attempts to schedule a phone call to discuss the matter further.
In any case, I will update this thread as new information comes in. Please share updates here as well.
Thank you
