I am using list automations to send direct messages in Slack to specific Slack users when a card is created or moved to a list they are responsible for. I have set this up successfully for two team members and myself, but despite following the same process and having the correct Slack member ID, the third team member is not receiving the messages.
Any ideas on what could be going on? As far as I know, there are no differences in permissions, etc. between the team members who are successfully receiving messages and the one who is not.
