The best part about messaging apps is that they send messages right away. Unlike traditional mail, which takes days, messaging platforms let you talk to anyone at any time. COVID-19 has made it possible for people all over the world to work from home, so companies are looking for reliable ways to send messages and news to their employees. If your company or team uses Slack, you may have noticed that messages are taking longer than usual to arrive.
From what we know, this happens on Slack when the number of users is too high for the servers to handle. Slack is one of the most popular apps for sending messages and sharing files. It helps employees talk to each other through voice calls and text messages. People often use the Slack app on their Android phones to get important notifications. Due to pending notifications for Slack on Android, all collaboration and messaging can be stopped.
There are a few things that could cause Slack notifications to be late. There can be problems with your internet, your phone’s settings for notifications, features that save battery life, etc. we’ll show you how to try different ways to Fix Slack Delayed Notifications on Android.
Fixed Slack Delayed Notifications on Android
Allow All Notifications
If you’re not getting notifications from Slack Channels, it’s because you haven’t set the Notification trigger. That’s because Slack’s default settings only let you know about direct messages (DMs), mentions, and keywords. To allow all notifications, you need to change this setting. Open the Slack app on your Android or iPhone, go to the You tab, and then click on Notifications. Under “On mobile, notify me about,” choose “All new messages.”
Enable System Notifications for Slack
If you have turned off app notifications in the Windows settings, Slack might not show pop-ups on your computer. If you accidentally turned off system notifications for Slack, here’s how to turn them back on:
- Press the Win key, type “search,” and then open the menu for notifications and actions.
- Scroll down and make sure the Slack app can send you notifications.
- Go to the bottom of the page and turn on notifications for the Slack app.
Enable Desktop Notifications from Slack’s Settings
Professionals use Slack more than any other instant messaging service, and you may have turned off notifications in the app’s settings. So, if you aren’t getting any alerts from Slack, check the settings app to see if desktop alerts are turned on. Here’s how it works:
- Open Slack on your desktop.
- Click the Menu button in the top left corner.
- Under the File menu, click Preferences.
- Open the Notifications menu in the Preferences section and choose the option for notifications called “All new messages.”
- If you’re not getting notifications after a certain time of day, scroll down and change the start and end times of notifications in the section called “Notification schedule.”
Enable Slack Thread Notifications
Are you not receiving thread notifications on Slack? Well, Slack has a dedicated setting for that as well that must be enabled. Open the Slack mobile app and go to the You tab > Notifications. Enable the toggle next to Thread notifications (iPhone) and Notify me about replies to threads (Android).
Disable Battery Optimization For Android
You might be having trouble with notifications because of how your Android phone is set up to save battery life. If you have Android version 6.01 or later, go to your battery settings and see if the setting to improve battery life is turned on. If this setting is on, your phone might not get alerts from Slack and other apps. To fix this, just turn it off. In particular, if you have Android version 9, make sure that the Adaptive Battery feature doesn’t get in the way of Slack updates.
Troubleshoot Slack
On Android and iPhone, Slack has a built-in troubleshooter for notifications that helps find problems. Open the Slack app on your phone to run it. Tap the tab that says “You” at the bottom, then tap “Notifications.” Tap Troubleshoot notifications to begin fixing the problem. If Slack finds a problem, fix it the way it says on the screen.
Check Notification Schedule Settings
Think of this as the Do Not Disturb (DND) mode built into Slack. Actually, this setting used to be called “DND mode only,” but now it’s called “Notification schedule.” When you join a Slack Workspace, the notification schedule setting is already on. So you will only get alerts during the day, and they will stop after 10 PM. One of the main reasons why Slack doesn’t send notifications is because of this.

To fix the problem, you need to change the Notification schedule setting and set the working hours to what you need. Keep in mind that Slack won’t send notifications outside of the times you choose. On Android and iPhone, open the Slack app and go to the “You” tab, then tap “Notifications.” Tap on the schedule for notifications.
