Hi,
Basically having the same issues as this person:
Set everything up properly (migrating from the old plugin). Setup the tester app with the JSON file. Enabled the debug stuff following amazon’s instructions:
I’ve tried using a debug keystore and my real one - makes no difference.
It always gets a “failed” state for the store.loadProducts() callback. The error messages returned don’t tell you anything other than “failed”. I know basically nobody uses Amazon IAP, but I’m hoping there’s at least 1 person with this issue!
