Pixelations

Why can't Directv Stream fix the random pixelations on local CBS station (WJTV-12) in Jackson MS area? This has been going on for over a month now and I have reported it to Directv and the station, but it is still happening. When I watch that channel on my package provided Paramount + it is clear with no pixelations which tells me the problem lies with the Directv Stream feed and not with my equipment or internet provider. Please fix this. Than You
