Hello, Over the past couple weeks we have been getting increased reports from our users who are unable to purchase IAPs within our app. Every time they go to make a purchase they are getting the 21107 error code. I haven't been able to find any concrete information about why users might be getting this error. The only thing that I have been able to find in the Apple documentation is: Status codes 21100-21199 are various internal data access errors. I did see some threads with this error code for people in sandbox accounts, but note that these are live users in our production environment. This is not internal testing. Users load the app, attempt to make an IAP purchase and they immediately get this OS error popup on the client and the purchase fails. We are using the Unity IAP package 4.10.0 If anyone has any information or suggestions it would be much appreciated.
