I tried to reply in Instagram but got the error message "Sending has failed. Your Instagram comment was not added - please verify its content"
This error message is sent to Brand Embassy directly from Instagram, as either your brand reached the maximum count of comments in a period of time or the content of your message is invalid.
If this error persists, please contact our Customer Support Heros.
PS: Don't forget to grab a print screen of the error message and console ;)
