Unable to connect TiVo MoCA network devices to the internet through my XB8 Gateway

I just upgraded my gateway to a XB8 gateway but am unable to connect my TiVo devices on my MoCA network through the gateway to the internet.  My MoCA devices were working well through my previous gateway (xFi Advanced Gateway).  I have researched my problem on the internet but can't find the information that resolves my problem.  My understanding is that the XB8 gateway does have MoCA enabled as a factory setting.  However, I cannot excess my gateway settings to confirm that MoCA is enabled.  The 10.0.0.1 URL does not allow access to the gateway settings anymore.  All you get is a window that tells you to download the Xfinity App.  And I have not found anyway using the Xfinity App to verify the MoCA setting in my Gateway.
