Purchased the product and it’s not working – Quran Al Kareem القرآن الكريم Review

I’ve purchased the full pack; however, a notification always pops up saying “just 2 first pages are free with this reciter, you can unlock the full pack for $4.99” Please help! It’s a great app but i cannot use it even though I have purchased the pack.
