I have purchased a texture pack inside the game in my daughter's iPad.

We have set up her account using Family Sharing, being the first purchase iOS requested to verify the purchase which was successfully done and the charge of $5.99 has gone through our card/bank account.

Upon returning into the Minecraft app, the texture pack is not available. Attempting to purchase it, Apple's systems detects that the item has already been purchased and will be restored for free. However the Minecraft app doesn't recognize this and it just stays with the loading graphics advising that "this shouldn't take long" (apparently indefinitely).
