The back end server of our system is supposed to update the prices of user-created in-app products for our Android app in Google Play store. The back end is written in C# and we use the "patch" service of Android Publisher to do that with the option "autoConvertMissingPrices" switched to "true".
https://developers.google.com/android-publisher/api-ref/inappproducts/patch
However, all it does is change the default price while the local prices stay unchanged. I guess we need something like the "overwrite existing prices" checkbox which is in the in-app products section of Google Play Developer Console but in the programmer's interface.
Any ideas would be greatly appreciated.
