Please note: Facebook Message Tags and One-Time Notifications (OTN) are ManyChat Pro features.
Please notice: if the Flow checked indicates that the Flow is fully compliant and doesn't have any issues in it, but the "Action needed" message still appears on the Dashboard - that indicates that highlighted Flows are being sent out outside the 24-hour window.
We've prepared several automatic options to check your bot and all the Flows for compliance with new Facebook rules.
Flow Checker can be found inside every Flow. It shows the messages that must be tagged to be sent to your contacts properly.
Also, you can check Messaging Window Compliance Monitoring available for all your accounts. This report helps you track bots that attempted to message someone after 24-hours since their last interaction without a specified reason.
Please note that ManyChat automatically blocks all the untagged messages sent outside the 24-hour window, so the bot wouldn't violate any rules. You are able to review the errors in the Flow and fix them before the next sending.
