Why does a Teams custom app notification bot need to be sometimes reinstalled in a Channel for the Channel to receive messages from the app again?

Question

We have a Teams custom app installed in a channel that we send notifications to from a web app. Sometimes, mainly between Friday and Monday, the app will stop showing these notifications in the channel. We have solved this before by reinstalling the app in the channel. We're currently testing the app but we would rather not have the risk of missing important notifications if we were go live.

We receive a 200 status in our web app from the teams app so it seems the app is up and running correctly, it's just not sending messages to the teams channel. Why would the app stop sending notifications to the channel?

Answer 1

The issue with your Teams custom app not sending notifications, especially between Friday and Monday, could be due to several factors.

1.Ensure that the notification settings in Teams are configured correctly. You can manage these settings by selecting your profile picture at the top right corner of Teams, then selecting Settings > Notifications. Make sure that the notifications for the channel where the app is installed are turned on.

2.Verify that the app has the necessary permissions to send notifications. This includes checking the app manifest and the permissions granted to the app in the Teams Developer Portal.

3.Check the health of the app in the Teams Developer Portal to ensure there are no reported issues that could affect its functionality.

4.Some organizations implement quiet hours or days where notifications are muted. Check if there are any such policies that might be affecting the app's ability to send notifications.
