Viva connections for mobile "Home page" button

Hi rafi1990,

Whenever you create a Viva Connections experience, you have the choice to assign a home site or not. If you assign a home site, that button will appear in mobile. 

Once the experience is created, there isn't a way to remove the home site from the web. There is a PowerShell command to remove a home site.

Remove-SPOHomeSite (Microsoft.Online.SharePoint.PowerShell) | Microsoft Learn

I've not tested the use case of removing a home site from an experience to see the results but that should be what you're looking for. I recommend testing this in a dev environment or a sandbox experience to be sure.

An alternative is to recreate your experience but choose the left option in the image above.

That button can be branded by assigning a logo to the site, but it can't be customized further.

Hope this helps!
