I'm not receiving notifications

Step 1 - Check your Ktkarena settings

This is the most frequent cause, especially after an update or a phone change.

1. Open Ktkarena, go to Profile → Notifications.
2. Check that push notifications are enabled for the types you want to receive.
3. If "Do not disturb" mode is enabled, disable it or check its time windows.
4. If "Vacation" mode is enabled, disable it.
5. Save.

Quick test: send yourself a test by tapping "Send a test notification" at the bottom of the screen. You should receive a push notification immediately. If yes, it was indeed a setting to fix. If not, move on to step 2.

Step 2 - Check the system permissions

Ktkarena asks for permission to send notifications on first launch. If you declined, the app doesn't have the system-level right to send any, no matter what your Ktkarena settings are.

On Android:

1. Android Settings → Apps → Ktkarena → Notifications.
2. Enable "Allow notifications".
3. For each Ktkarena notification category, check that it is enabled individually.

Quick test: run the test again from the Ktkarena app. If it works, it was the system permissions.

Step 3 - Disable battery restrictions

Many Android phones (especially Chinese brands and Samsung) have very aggressive battery management that kills apps in the background to save power. Ktkarena can then no longer receive push notifications.

On Android (varies by brand):

• Samsung: Settings → Device care → Battery → Background usage limits → Never sleeping apps → Add Ktkarena.
• Xiaomi/Redmi: Settings → Apps → Manage apps → Ktkarena → Battery saver → "No restrictions".
• Huawei: Settings → Battery → App launch → Ktkarena → Disable "Manage automatically" → Enable "Auto-launch", "Secondary launch", "Run in background".
• OnePlus / Oppo / Realme: Settings → Battery → Battery optimization → Ktkarena → "Don't optimize".
• Stock Android (Pixel, Motorola): Settings → Apps → Ktkarena → Battery → "Unrestricted".

Step 4 - Network diagnostics and reporting

If the first 3 steps aren't enough, there's a deeper issue.

Check your connection:

• Do you actually have internet? Open another app (WhatsApp) to confirm.
• Are you on a network that blocks push notifications? Some corporate WiFi networks filter Google push services. Try on 4G.
• Are you using a VPN? Disable it temporarily to test.

Force a push token refresh:

1. In Ktkarena, go to Profile → Notifications → Diagnostics.
2. Tap "Regenerate push token". This forces the app to request a new token from the system.
3. Run the test again.
