| ###### Solution | ||
| The known and effective workaround is to explicitly force altool to use the correct app ID by passing the argument: ```--apple-id <app-apple-id>```. We’ve added support for an optional ```--altool-additional-arguments``` option to the app-store-connect publish action. This allows you to pass any additional CLI arguments directly to altool. You can also set this via the environment variable: ```APP_STORE_CONNECT_ALTOOL_ADDITIONAL_ARGUMENTS```. Your app's Apple ID can be found in AppStoreConnect > General > App Information > Apple ID |
