Question: I configed slack from ISD UI. Not getting any alerts in slack

Answer: Spinnaker has a defect due to which it is not de-crypting the token. Please manually update the token in hal/config file in the repo in plain text or use the "encrypted:SECRET-NAME:SECRET-KEY" format for using kubernetes secret.

There was a defect in the past where "name:" tag was placed for slack-configuration in the config file. Please delete it if it is present. Only one slack account needs to be configured...for sending notifications to multiple channels.
