I have developed a messenger bot and also got approval for the page_messaging from facebook and it works great. Now as per the Facebook terms and guidelines for subscription messaging mentioned here(https://developers.facebook.com/docs/messenger-platform/policy-overview#subscription_messaging) for Standard Messaging means the page_messaging permission which we have it says:
"Messages cannot be sent beyond 24 hours from any triggering action, as described above. Exceptions include template messages and one additional bonus message outside of the 24 hours to follow up on the conversation."
Here it's clearly mentioned that template messages are exceptional and can be sent even after 24 hour period but when we are trying to send message after 24 hour it is asking for subscription permission and giving following error:
{"error":{"message":"(#230) Requires pages_messaging_subscriptions permission to manage the object","type":"OAuthException","code":230,"fbtrace_id":"FAfXwRoT\/ta"}}
So, when facebook says that the template messages are exceptional and can be sent after 24 hour period then why it is giving subscription permission error for template message?
Any help will be appreciated. Thanks in advance.
