What is causing the Slack notifications to stop functioning?
We investigated this particular issue on Windows by looking at various user reports and the repair strategies that some affected users have deployed in order to resolve the problem. Based on what we gathered, there are several fairly common scenarios that will trigger this particular issue: If you’re currently looking for troubleshooting steps that will fix your Slack notifications, this article will help. Down below, you’ll find a collection of methods that other users in a similar situation have used to correct this broken behavior. The methods are ordered by efficiency and severity, so please follow them in the order that they are presented. One of them is bound to resolve the issue in your particular scenario.
Method 1: Read all your pending messages
If you’re no longer receiving Slack notifications (but you used to see them), chances are your operating system has determined that those messages are not that important to you so it stopped sending them. This is a new feature introduced with Windows 10. If this particular scenario is what’s causing the lack of Slack notifications, the fix is to simply read all pending Slack messages. This will send the right signals to Windows 10, making it aware that you’d like to receive more in the future. With this in mind, simply open your Slack application (desktop or UWP) and click on each new messages to read it. Once every message has been read, close Slack and restart your computer. If Windows was previously considering Slack notifications as not important, this behavior should have changed now. Once the next startup is complete, monitor Slack’s behavior and see if you start receiving notifications. If you still can’t see Slack notifications, move down to the next method below.
Method 2: Make sure that desktop notifications are enabled
If you never received Slack notifications, chances are this functionality is disabled from Slack’s Settings menu. Keep in mind that workspace administrators have the ability to change the default notification behavior. Even more, notification settings are not application wide – If you’re part of multiple workspaces, you’ll need to establish default behaviors for all of them. Here’s a quick guide on making sure that desktop notifications are enabled on Slack: Note: The steps below will work on both the desktop and the UWP version of slack. If you still can’t see notifications even after ensuring that notifications are enabled for your application, move down to the next method below.
Method 3: Disabling or adjusting the Do Not Disturb Mode
Another potential setting that could end up disabling your Slack notifications is the “Do not disturb” mode. While this mode is turned on, Slack will not send you any notifications. This setting is typically adjusted by the workspace creator according to the team member’s time zone but can be overridden quite easily. If you’re in a completely different time-zone than the one established by the workspace creator, that could be the reason why you don’t see any notifications. If this scenario is applicable to your situation, here’s a quick guide on modifying the “Do Not Disturb Mode” settings accordingly: If you’re still not receiving notifications on Slack, move down to the next method below.
Method 4: Clearing the Slack application cache
As it turns out, failure to show notifications can also be traced back to a Slack application cache error. Several users struggling to resolve the same behavior have managed to get the issue resolved by clearing the Slack application cache. Slack stores cached data to speed up the loading times and improve on the user experience. But as a lot of user reports have shown, as cached data piles up, you might start seeing negative effects (including the disappearance of the notifications or large delays). Fortunately, it’s quite easy to clear the cache is quite easy, but the procedure is different depending on what version of Slack you’re using. Please follow the appropriate guide depending on which Slack version you’re using:
Clearing Slack’s cache for UWP version
Clearing Slack’s cache for Desktop version
If you’re still not receiving any notifications even after clearing the application’s cache, move down to the next method below.
Method 5: Reverting back to the previous notification behavior
Several affected users have reported that the issue was fixed after they disabled Slack’s integrations with Windows Action Center and reverted back to the previous notification behavior. This can be done quite easily with a simple Run command. Here’s what you need to do: If you’re still unable to see Slack notifications, move down to the next method below.
Method 6: Disabling Quiet Hours (Focus Assist) on Windows
Another popular reason why you might be seeing this particular issue due to a Windows productivity feature called Quiet Hours (rebranded as Focus Assist). If you didn’t know, this feature will disable all notifications during a set time that you get to configure yourself. The Quiet Hours feature works as a master filter, meaning that it will override any application settings (including Slack). So even if you have Slack configured to display a notification for every event in your workstation, Quiet Hours will disable them all. Note: Quiet Hours is only available on Windows 8.1 and Windows 10. If you’re suspecting that Quiet Hours might be causing this particular problem, here’s what you need to do:
