NightmareRambo77, yes. There are two different apps:
- The Viva Connections desktop app that was released in March, as a custom LOB app that leverages the PowerShell script we made available to create the app package for it. Details on this app are here: Add Viva Connections desktop to Microsoft Teams - SharePoint in Microsoft 365 | Microsoft Docs. Note that this app supports ONLY the desktop experience.
- The Viva Connections first party app that is currently rolling out and will automatically be available in Teams app store in tenants. This app includes both the desktop experience AND the mobile experience for Teams apps for iOS and Android. The app can be configured directly in Teams Admin Center (e.g. update the name, icon, theme color) without the need to create and upload an app package.
If you are already using the LOB app, it will continue to work. When you are ready to switch to the first party app, you can block the LOB app, and allow the new one.
Hope this helps.
