@Sme1 there is no optimisation setting on Sky hubs. I would fully reboot the TV by turning the mains off until the power led goes out. That alone often sorts issues like these. If it doesnt tgere is not much you can do except check the setting for Sky's Broadband Shield in the My Sky app as if set to a low age it can block certain apps.
