Vodafone Power Hub

I am having problems using the power hub UI

Some switches won't toggle and when they do you can't apply the changes.
Refreshing the browser sometimes helps but not always.
I have made most changes but have one that I can't make no matter how many times I refresh the browser and that is to disable WPS. The page that you do this on is competely non responsive, buttons don't work and I can't turn WPS off.
I have tried numerous browser including, Opera, Edge, Firefox, Chrome.

Mine is the same, I've given up trying to turn off WPS. Must be a firmware bug.

Thanks for your reply with which I agree.
