basic to pro upgrade

[bill123]

Hi
I bought the basic version for ipad and would like to upgrade to the pro version but AppStore keeps asking for the full price without deducting what I've already paid. How do I do the upgrade please?

Hi,

if you tap the version "PRO VERSION" you can hit upgrade if you want to buy the upgrade or hit restore if you want to restore to the upgraded version you already bought.

Best,

Thomas
