I have a problem with my login screen - well actually it is with the screen that comes before the login screen.
It seems to be stuck on the colour that is chosen for pesonalisation/colour/pick a colour. Although my lock screen is set on windows spotlight (it is my understanding that the screen loaded before the login screen and the lock screen picture share the same image - this was true a few builds ago but now the screen in question just seems to stay the solid colour. I have also notice that if i go to personalization/lock screen that the apps that I can choose to show detailed status and the other plus signs - the drop down lists are all blank, some with red X s on them.
