FYI, a Ring chime is NOT required. Ring doorbells are made to work with your existing chimes. As long as they're still functioning and wired properly, they should work with your ring.

I also have the Ring Pro.

Like others mentioned, a strong wifi signal, and I do mean STRONG signal where your Ring is installed is required to get the best resolution and reaction times. Don't expect your rented comcast modem placed on the other side of the house to give you an adequate signal.
