Despite installing all the latest updates, SkyQ apps are still pixelating

[Fio3]

Installed the latest updates (to the one they said should solve the problem), updated all of my apps, and yet the apps are still pixelating, though not nearly as bad as before, but still ruining my viewing experience, on platforms that I pay good money for. C'mon Sky, get this sorted once & for all, you're happy to take peoples money, but customer service is at rock bottom.
