Purchased but cannot access pro features

I love the app but its a ripoff that i paid five dollars only to not be able to use the features it advertised. It keeps sending me to a redirect page to upgrade which i have and when i "restore" my purchase it says i already bought it. But will not activate any features.
Keeping 1 star until this is fixed. Its terrible
