This issue occurs when your application is built with a Provisioning Profile for a Bundle ID that does not match the Bundle ID of the uploaded certificate that you uploaded to OneSignal.
You may have created several assemblies of your application, some with the correct package ID, and some with the wrong one. As a result, you may have signed devices in OneSignal that are associated with different package identifiers.
If you can receive notifications with the latest version of your application, you can probably ignore this error. If all the iOS notifications you send are displayed as “Invalid,” you must either upload a new push certificate with the correct package ID, or create your application with a provisioning profile that matches the package ID of the push certificate.
