I think it’s more likely that it’s an authorisation problem that is occurring with many cloud to cloud services for UK customers right now. This includes IFTTT, for example, as well as smarttiles and sharpTools.
The problem is that the authorisation process for outside services is being directed to the US servers, and since your information is on the UK servers, no authorisation can be performed.
The only thing you can do about this right now is report it to support. That way they can let you know as soon as a fix is found.
