I have updated the label to the channel name, why can I still not receive tickets in Slack?

Please note the label is not the slack channel name, in this case, no ticket will be received in the Slack channel. Please use "default" if you have toggled on "Default" for that slack channel in the Broadcast Group Settings.
Please refer to the documentation here for more details.
