Any ideas FUBO carrying ESPN at 30 FPs instead at normal 60 FPs?

[N5XZS]

I noted ESPN 1 and 2 are sent in 30 FPs instead of Normal 60 FPs on FUBO streaming service?

I find it annoying seeing slight video judders and no smoothness.

While FOX Sports 1 and 2 are shown at normal 60 Fps on FUBO?

Is there a tech, problem or contract deal for bandwith cost?

I am on Xfinty at 500 MBs.
