I know at least 1 other is suffering with this issue.
I go onto rumpel (tried on both phone and desktop - one windows one IOS with different browsers it was also tried, google IE, safari) and I click the link next to the data plugs and it says 'are you sure'? and mentions i'll navigate away from Rumpel. I click yes, it then does nothing and just stay on the page I was on.
So I can't connect any of my data plugs at the moment.
