You can refer to this Announcing MBaaS Service Retirement on
February 3rd, 2020 by John Wargo from Principal Program Manager, Visual Studio App Center .That is an official announcement.
Earlier last year, we launched the App Center Auth and Data services in early preview. Together with App Center Push, the three services form the App Center Mobile backend as a service (MBaaS) offering, and give developers an easy entry into using Azure as a backend for mobile apps.
As a result, we are discontinuing efforts in the Auth, Data, and Push services and working to retire these preview services in App Center. With this change, we will focus App Center on delivering a world-class mobile and desktop DevOps experience. We will also work together with Azure teams to help migrate developers to the native Azure services, and ensure that Azure continues to be a great platform for your mobile apps.
What This Means to You
Your apps can continue to use these services for now; we want to give you ample time to consider, and implement other options for your apps before we retire the services.

After this date, the Auth and Data services will no longer be available in the App Center portal; the services may continue to operate for a short while after this date, but you will not be able to interact with either service using the App Center portal UI.
App Center Push Retirement Timeline
Microsoft is committed to providing the best notification offering possible and we think the best way to do this is to focus our efforts on a single offering in Azure Notification Hubs. We know many of you value the unique features unique to App Center Push and we want to offer similar capabilities in Azure Notification Hubs. With that in mind, we’re working to create a transition plan which causes the least disruption to our existing customers as they move to Azure Notification Hubs.
