Hello, upon clicking Take Action when trying to reconnect to HMRC (have been connected / done VAT returns fine previously) the pop up window that opens says:

{"Message":"You do not have the proper permission to access that feature.","dojoLocale":"en-gb","state":"Error"}

and that is all, so I can’t re-connect to re-authorise MTD.

Any help? Many thanks! 

(Have tried to disconnect and reconnect to HMRC under Settings > Advanced (said HMRC connection was ON)
