XFi not allowing android phone to sync

While at home and using XFi , (XB6 + 3 Pods), my Samsung S10+ (Xfinity Mobile) doens't sync. I do not have cell coverage at my house so I figured that using Xfinity Mobile with Wifi Calling should be great, but as soon as I leave the house and get a good signal, my phone starts syncing across all the different apps. This doesn't happen at other locations where I connect to wifi, but only when XFi is controlling the network. Any Ideas or suggestions would be great.
