ovr_GetLoggedInUserID always return 0
const char* appID = "the-app-id"; if (ovr_PlatformInitializeAndroid(appID, androidApp->activity->clazz, Env) != ovrPlatformInitialize_Success) { ALOGE("Failed to initialize Platform sdk."); exit(1); } ALOGV(" my logged in user ID is: %lu ", ovr_GetLoggedInUserID()); const char *sku = "unpublished_item"; ALOGV(" launch checkout flow "); ovr_IAP_LaunchCheckoutFlow(sku); I am having trouble setting up the SDK in my OpenXR app. The initialization is successful, however I always get ovr_GetLoggedInUserID as 0. And the ovr_IAP_LaunchCheckoutFlow will end up with an error "Received launch checkout failure: An Unknown error occurred" Is there anything I am missing?
