The key is not valid or is not compatible with the Bundle ID of your app.

Hey ​@garet-drouin-2effa6 ! Sorry to hear you’re facing this.

It seems that the validation could be stuck in an odd state - to try and see if that is the case, could you please try and replace the current .p8 file that you have added in the “In-app purchase key configuration” with a temporary (e.g a “fake” one, or a duplicate) one, just to be able to save the changes?

Then replace ir with the “real” one once more (and saving changes), to see if that helps in triggering the validation from the start.

Let me know if that helps at all!
