On an iPhone, you can easily set notifications in the menu on the left. We recommend that you always allow them so you don't miss important messages. If you have an Android, do this: (1) hold the app icon until a list appears, (2) press app info, (3) check that notifications are allowed. Reinstall the app if it doesn't work.
If notifications don't work on Android even after you've completed the three steps and reinstalled the app, try to clear the cache in Google Play Store and install the latest version of the app. Follow these steps:
- From a Home screen, navigate: Apps > Settings > Apps. If unavailable, navigate: Apps > Settings > (Applications) Application manager. For Oreo OS, navigate: Apps icon > Settings > Apps & Notifications > App info.
- Tap Google Play Store.
- Tap Storage.
- Tap Clear Cache then tap Clear Data.
- Tap OK.
