PDF.js Express Viewer  
Version - Any  
Trying to create a free key for a .co.uk domain but it says “You already have a license key for that domain”. The domain I am trying to add is NOT listed there in the Subscriptions. Another .co.uk was added ok previously some weeks ago but I now need to add an additional one.
