A. 1. Check your internet connection: Ensure you have a stable Wi-Fi or mobile data connection. You can do this by opening a web browser and trying to load a website. If the connection is weak, try moving closer to your router or switching to a different network. 2. Clear the app cache: Go to your device's Settings > Apps > VK > Storage > Clear Cache. This can help resolve any temporary issues that may be causing delays in message delivery. 3. Update the app: Make sure you are using the latest version of VK. Go to the Google Play Store, search for VK, and tap 'Update' if available. Updates often fix bugs and improve performance.

B. 4. Restart the app: Close VK completely and reopen it. This can refresh the app and potentially resolve any temporary glitches causing message delays.
