Our app was rejected yesterday for this same reason, but Apple is just asking for more information from us. I expect that when we answer their questions, they will resume our review. Did you answer their questions and find that Apple subsequently rejected your app and insisted that you use their "Apple Business Manager" for distribution? Here is the rejection reason: From Apple 2. 1 Performance: App Completeness Guideline 2.1 - Information Needed We’re looking forward to continuing our review, but we need a bit more information about your business model and your users to help find the best distribution option for your app. Our preliminary review of your app suggests that your app may be a good fit for our Apple Business Manager program, which is designed specifically for business apps.  Next Steps Please review the following questions and provide as much detailed information as you can for each question.   Please describe which kinds of users you expect will use your app. Some common kinds of users are: Users who are part of a single company (including its partners, employees and contractors) A limited number of companies which are clients of the developer The general public Identify the specific countries or regions where you plan to distribute your app. What features in the app are intended for use by general App Store users? How do users obtain an account? If there are any paid aspects of the app, such as for opening an account or using certain features in the app, please explain how users access the paid content. Who pays for the paid content?

We have several thousand enterprise users who use a variety of MDM packages, including MobileIron, IBM MaaS360, Apple Configurator, AirWatch, and Microsoft Intune. ALL of them are experiencing this crash of our Xamarin.iOS app if the device is running iOS 14.2.
