Didn't receive the upgrade and they took my money regardless
Bought pro for 1 month for the purposes of using this on holiday. It took 2.5 weeks to receive the upgrade from free version which was therefore too late. I requested a refund which has not been provided despite my best efforts. They hide behind 'You've purchased it through apple so it is up to them whether it is to be refunded' apple will not allow refunds either.
Therefore they have taken my money and all i have received is the hinderance to try and solve the issue.
