I have the same problem that was raised in this post, but unfortunately I am unable to view the replies:
Essentially, I would like to get a notification when I have been added as Point of Contact on a table, but as the doc owner I am not receiving a notification in either Coda or Slack (where I currently have integration).
The same interaction undertaken in a table owned by another doc sends me the notification.
In your use case, you can limit the choice for your column “Point of Contact”, and when someone adds you, you will get a notifications. Any other people added in this column would also received a notification
The second option will be to create an automation, looking for a change in “Point of Contact” column, with condition that is you. Then you only send a notification to yourself
