If you are not receiving Slack notifications, please check the following

If Slack notifications are not coming to the selected channel,

Please add the bot manually to the specified channel again (post "/invite @Jicoo" to the corresponding channel).

Slack notifications are sent using the Slack integration of the member who is assigned to the booking. This also applies when you have specified a channel for notifications on the booking page. Every member who could be assigned to a booking should connect Slack from Integrations. If a booking is assigned to a member who has not connected Slack, neither the individual notification nor the channel notification is sent.

If Slack credentials fail to refresh, the service integration screen can keep showing “Connected” while notifications are no longer sent.

In that case, disconnect Slack from the service integration screen and connect it again. After reconnecting, please also check your notification channel settings.
