In the meantime, we recommend using Meta Business Manager as a workaround for creating and submitting templates. Additionally, we advise refraining from performing migrations, onboarding, and template-related actions for now. This will help prevent the limit from being reached immediately once the issue is resolved and ensure a smoother experience when the systems are fully operational again.
We greatly appreciate your patience and understanding during this time, and we will continue to provide updates as soon as we have more information.
