Same here – I initially lost Netflix and YouTube this morning.
I tried a full retune, clearing the cookies and a few other things, however I was unable to accept the “Privacy Policy, Terms and Conditions” – the page remained blank at all times.
Finally, I did a factory reset (keeping recordings) but it still doesn’t work. The “Privacy Policy, Terms and Conditions” page remains blank and all the Apps (including iPlayer) are now lo longer available.
However, I am able to access iPlayer by pressing the Red Button whilst on a BBC channel and I was successfully able to watch a program on the iPlayer so it proves that I am successfully accessing the internet (however the iPlayer option still remains absent from the menus).
