There is an issue with the price-setting on in-app purchases. The interface for setting the price of an IAP is out of sync with what is actually set. For instance, I changed the price to $6.99 and in the app it displayed $7.99. Later I changed it to $5.99 and the app displayed $6.99. I think the frontend is setting the wrong value in the backend (database).

Since yesterday I'm not able to make any changes (localizations, review screenshot, etc.) to the in-app purchases I'm about to ship with the next app update. It takes minutes for the in-app purchase websites to fully load. When adding a localization by hitting the "create" button it also takes very long to finish and most of the time it will not save the changes. It looks like this part of App Store Connect is broken. I thought it was only a temporary problem, so I stopped bothering yesterday and hoped for the issues to be resolved today. The problem is not "my poor internet connection". In fact, my internet connection is very good. I've tested with Vodafone fiber (1 GBit/s), Telekom Fiber (100 MBit/s) and Vodafone 5G. All the other parts of App Store Connect work fine as far as I can tell. Maybe someone can look into this.
