Apple Internet Accounts AAD Enterprise App is using deprecated API

In an O365 environment, the Azure AD Enterprise App 'Apple Internet Accounts' (earlier name: iOS Accounts) is created to enable Apple's native 'mail' app to access your mailbox.

The problem is, it utilizes the 'Windows Azure Active Directory Graph' instead of the newer, Microsoft Graph API to "sign in and read user profile". According to Microsoft, “Azure AD Graph is deprecated. To avoid loss of functionality, migrate your applications to Microsoft Graph before June 30,

2022 when Azure AD Graph API endpoints will stop responding to requests." - then they delayed the change: "We are not retiring Azure AD Graph API on June 30, 2022. Listening closely to the challenges of migrating such a critical dependency, we’re delaying the retirement date through at least

the end of this year (2022). "

What will happen at the end of the year, will I still be able to use native mail in O365?
