The application does not pass moderation in the App Store, what should I do?

Question

Apple Developer Program

Greetings! We made applications for iOS, the functionality is simple: the application opens the web url of the mobile version of the site. At the same time, it additionally implements a basket in the form of saving links (opens the product when clicked), push notifications. Around the 20-25th of December, the application was sent for moderation. We waited a very long time for an answer. The answer came only on January 9-10. The application was rejected, citing the fact that their conditions have changed and now only native applications get into the store. At the same time, we did not receive any statements, mailings and other things about changing the conditions at the time of the development of the application.
How to be? Writing a native application for our online store is expensive and time consuming.
The official answer is a disclaimer from Apple:

Your app provides a limited user experience as it is not sufficiently different from a mobile browsing experience. As such, the experience it provides is similar to the general experience of using Safari. Including iOS features such as push notifications, Core Location, and sharing do not provide a robust enough experience to be appropriate for the App Store.
We've attached screenshot(s) for your reference.
Next Steps
Please revise your app to provide a more robust user experience by including additional native iOS functionality.
If you cannot - or choose not to - revise your app to be in compliance with the App Store Review Guidelines, you may wish to build an HTML5 web app instead. You can distribute web apps directly on your web site; the App Store does not accept or distribute web apps.
HTML5 is the major new version of HTML and enables audio and video to play natively in the browser without requiring proprietary plug-ins. Using HTML5, web apps can look and behave like native iPhone and iPad apps, and using HTML5's Offline Application Cache, a web app can work even when the device is offline. With web apps, you have the flexibility to deliver as much or as little functionality as you desire.
To get started with iPhone or iPad web apps, please review the Safari Client-Side Storage and Offline Applications Programming Guide.

Answer 1

Everything was written to you correctly, your application does not bring any benefit to users. So either forget or make a native app.
By the way, since December 25, Apple had a vacation. So they didn't work at that time. This was announced in advance.
