Please can anyone help, I can’t progress past half-way through ex 7 , despite following instructions , resetting , starting over etc . Know its a problem experienced by others in past but non of the workarounds mentioned here are working just won’t ‘un-grey’ and move on .Was really enjoying the course just gutted now can’t complete. Tried different browsers too. Was complementing upgrading to Pro but if freebie doesn’t work am now wary parting with cash ! Thanks.
