Hey @haosongma! Would you mind updating your question with some screenshots and logs of what you’re seeing?
As for why you’re running into issues with Expo, that is because Expo generally doesn’t work with React Native native modules. Since our In-App Payments React Native plug-in wraps the native Android and iOS SDKs and binds them using the native module, it doesn’t work with Expo.
Hi, there is a screen shot. Could you see that?
Ah yes, I can see it now. Not sure why that wasn’t displaying before.
