Start with the simple checks. Change one thing at a time so you can tell which step helped.
Notifications may be muted by focus mode, denied permission or restricted background activity. First, note what changed recently and whether the same issue affects another device. This helps separate a device-specific fault from a wider network or service issue.
Troubleshooting steps
Check the basics
Check the app’s notification permission in the phone’s system settings. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Review the settings
Review Do Not Disturb, Focus or scheduled quiet-time modes. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Test one change
Open the app’s own notification settings and confirm the relevant categories are enabled. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Confirm the result
Check battery saver and background data settings if alerts arrive only when the app is open. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Helpful note
Menus vary across Android versions and phone makers, so use the settings search if needed.
When to get more help
If these checks do not resolve the issue, contact the relevant device maker, internet provider or app support team. Include the exact model, software version, any error message, what you have already tried and when the problem began. Avoid sharing passwords, verification codes or private account details in a public forum.
For equipment that is hot, damaged, wet or making unusual electrical sounds, stop using it and seek qualified support. Do not open power supplies, batteries or mains-powered equipment.
Settings and menu names vary by model and software version. Use the manufacturer's current instructions for device-specific steps, and back up important files before making changes that could remove data.
