I have changed the price of one of my in-app purchases from Price Tier 1 (Paid) to Price Tier 0 (Free) - this is to encourage people to download the app when I promote it.
The problem is, however, is that I changed it a few hours ago and the app is still showing the Price Tier 1 price for the in-app purchase.
How do I fix this? - Is an app update needed to cause this price change to happen? - If so how can limited time promotion be done?
