the Messages page lists your texts, the Photos app shows all media from your device's gallery, and the Calls tab allows you to view your recent call activity. Select one of the tabs and the Phone Link app will populate its contents on the screen, i.e. There are 3 tabs that you can jump to: Messages, Photos and Calls. Microsoft has moved these tabs to the top of the window. It is no longer home to the various sections that you could navigate in the old version. The side panel on the left has been revamped, and displays the notifications received from your phone. Use the buttons at the top to enable/disable Do Not Disturb Mode, Bluetooth, Volume, and control the Audio playback. The app displays the name of the connected device, along with icons to represent the strength of Wi-Fi and Mobile Networks, and the Battery level. The Phone Link app on has rounded corners, new icons to match Windows 11's design. Microsoft renames Your Phone Companion to Phone Link

This is not an April Fool's Day prank, the app's name has really been rebranded.
