Today, I am facing the same issue with my HN reader app - HackerNewsX [2] Using search feature reviewer found stories containing COVID keyword and flagged app as a breach of 'Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage' [3]
> Per section 5.1.1 (ix) of the App Store Review Guidelines, apps that provide services or collect sensitive user information in highly-regulated fields, such as healthcare, should be submitted by a legal entity that provides these services, and not by an individual developer.
Please advise how I can negotiate with Apple and resolve this matter.
