“User does not have permission for this action: The user does not have permission for this action”

Please check if the Meta profile used for ad account connection still has admin rights to the ad account you have selected when creating a rule.

For example, the screenshot below shows that Alla has admin rights to the Birch Meta ad account (in your case, your profile should have admin toggles on for all the Meta ad accounts you need to use here).

​

Please note that it’s important to check specifically profile through which ad account is connected to Birch in Platforms section. Once checked, please reconnect the Meta profile to Birch (while logged in to Meta under the same profile).
