Apple project publishing on store with problems

I'm trying to publish my first app to the store, but I'm having problems. I wish someone could help me resolve these errors received from Apple Store. After carrying out the analyzes by the Apple Store I receive this message: Thank you for your resubmission. Upon further review, we identified additional issues that need your attention. See below for more information. If you have any questions, we are here to help. Reply to this message in App Store Connect and let us know. Guideline 3.1.1 - Business - Payments - In-App Purchase We noticed that your app includes or accesses paid digital content, services, or functionality by means other than in-app purchase, which is not appropriate for the App Store. Specifically: - Your app accesses digital subscription features purchased outside the app, but the subscription isn't available to purchase using in-app purchase. Next Steps The paid digital content, services, or subscriptions included in or accessed by your app must be available for purchase using in-app purchase. If you have any additional information to provide regarding the digital content and services in your app and how the guidelines apply to them, please reply to this message in App Store Connect and let us know. If there is information you'd like us to consider in our review of future submissions, please feel free to include it in the App Review Information section of App Store Connect. Resources - See how to implement in-app purchase with the StoreKit framework. - Review step-by-step instructions for creating in-app purchases in App Store Connect. - Learn more about our policies for apps that offer paid digital content and services. Guideline 4.3 - Design We noticed your app shares a similar binary, metadata, and/or concept as apps submitted to the App Store by other developers, with only minor differences. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps. Next Steps Since we do not accept spam apps on the App Store, we encourage you to review your app concept and submit a unique app with distinct content and functionality. Resources Some factors that contribute to a spam rejection may include: - Submitting an app with the same source code or assets as other apps already submitted to the App Store - Creating and submitting multiple similar apps using a repackaged app template - Purchasing an app template with problematic code from a third party - Submitting several similar apps across multiple accounts Learn more about our requirements to prevent spam in App Store Review Guideline 4.3. Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage We noticed that your app requires users to register or log in to access features that are not account based. Apps may not require users to enter personal information to function, except when directly relevant to the core functionality of the app or required by law. For example, an e-commerce app should let users browse store offerings and other features that are not account based before being asked to register, or a restaurant app should allow users to explore the menu before placing an order. Registration must then only be required for account-specific features, such as saving items for future reference or placing an order. Next Steps To resolve this issue, please revise your app to let users freely access your app's features that are not account based.
