Why are chat notifcations delayed?

and also an indicator for when a message has been read in private chats and channels

When I am replying to a message, in channel and private chat, or if I minimize the ios app, and a reply notification pops up, i click it, it doesn’t show up. I have to swioe away the message thread and go back to the reply thread. Please fix this! It used to work! the events don’t ever appear on the overview section on the home tab. It doesn’t show the events, like it does on the desktop client. It should also show for all events including events that don’t have a zoom link.

There are a few reasons why you might be experiencing delayed notifications on your iPhone, and some troubleshooting steps you can take to fix them:-

1. Silent mode - Make sure your phone isn't on silent mode [Do Not Disturb mode].
2. Individual app notification settings - Verify that notifications are enabled for the specific apps you're having trouble with. Go to Settings > Notifications and select the app to check its notification settings.
3. Network connection - Ensure your iPhone has a stable Wi-Fi or cellular data connection. Notifications rely on data to come through.
4. Restart your iPhone - A simple restart can often resolve temporary glitches that might be causing notification delays.
5. Update to the latest iOS version - Outdated software can sometimes lead to notification issues. Check for updates in Settings > General > Software Update.
6. Low Power Mode - Low Power Mode can reduce background activity, which might delay notifications. Try disabling it in Settings > Battery.
7. Background App Refresh - Restricting Background App Refresh for certain apps can delay notifications for those apps. Go to Settings > General > Background App Refresh and check the settings for the affected apps.
