Do note, template approval can take upto 24 hrs. This entire process is managed by you with Meta directly. You can also view your Meta templates on Plivo Console. By clicking on ‘Sync Templates ..’ button, you can fetch the latest template details from Meta. This view also gives you visibility into why your users are blocking your messages.
