Live view using cellular even when connected to wifi

I noticed recently that even when I am connected to wifi, running live view seems to use cellular data! When I restrict the app from using cellular data from the iphone settings it seems to work fine on wifi . When I switch it back to allow for cellular usage (again, my phone is still showing that it is connected to wifi), the ring app goes back to using cellular. I tried turning off the iPhone's `Wifi Assist` function, thinking that may be what is happening, but still, it seems to be using cellular data. Anyone else seeing this? Thoughts? (I am measuring this by looking at the app statistics under the "Cellular" section of the iPhone settings - it shows how much cellular data each app is using. I reset the stats before each test)
