I am in the same situation! Built a news app and got rejected for the same reason. I am constantly explaining that it does not collect any user data and I get the same response in the resolution center every time: Hello, Thank you for your information. Regarding 5.1.1, we still found that your app provides services or requires sensitive user information related to the COVID-19 pandemic. To resolve this issue, your app must be published under a seller and company name of a recognized institution. For additional details, please refer to the update on the Apple Developer website about Ensuring the Credibility of Health & Safety Information. I am sure there is no real human reviewing these apps because I did not get any real reponse yet. It all looks very automated which makes it so frustrating

Same situation, they don't explain there reasoning at all, so frustrating
