A. 1. Check notification settings: Go to your device's Settings > Apps > VarageSale > Notifications and ensure that notifications are enabled. 2. Enable background data: Go to Settings > Apps > VarageSale > Mobile data and ensure 'Allow background data usage' is turned on. This allows the app to receive notifications even when not actively in use.

B. 3. Check battery optimization settings: Go to Settings > Battery > Battery optimization, find VarageSale, and select 'Don't optimize'. This can help the app run in the background more effectively.
