Sometimes Facebook revokes access to the account due to security reasons so the connection with Revealbot is lost. You might see the pop-up error at the bottom of your page in Revealbot account: An issue occurred while analyzing your Facebook account. Please reconnect it to make sure it works properly.
Try re-authenticating your Facebook profile using this link: https://revealbot.com/auth/facebook?auth_type=reauthenticate
If you would like to receive notifications about connection lost in Slack, please ensure that you have added a Slack channel in your account settings:
With this setting enabled, you will receive notifications via Slack whenever the connection to Facebook, Snapchat, TikTok or Google Ads is lost, so you will be able to restore the connection on the Integrations page by clicking into the respective platform name and "Reconnect" button.
Note: If there are several FB profiles connected and you have already reconnected yours, make sure the other users did the same - if you just disconnect a profile, all rules associated with it will turn into drafts.
