I’ve automated a lot of messages thanks to Coda, but, recently, I’ve noticed a downgrade in Coda-Slack messaging feature.
The messages I’ve sent from Coda don’t appear in Direct Messages column in Slack so I can’t track to whom I’ve sent messages. I hope this gets fixed ASAP.
When you set up your button to send the message through slack what credentials do you have set up in the settings of that pack to push the message? Slack should be associated with the persons email with direct messages to them through the slack pack. I would encourage you to reach out to support and share your doc with us so we can take a closer look for you.
