If Hiya is not working correctly in general there are a couple things you can try.
Update the app in the App Store:
If you still have issues, try the fail-safe described below.
If you are on an older version of the iPhone operating system, you may not be able to update to the most recent version of the app. Please update the phone to a more recent version of iOS to update the app. We are only compatible with iOS 13 or above.
Please note that this step may update your app to the free version of our app. The premium version is available within the updated app.
Do not force quit the app during everyday use: Hiya needs to do updates periodically and if the app is forced closed in the middle of the update then blocking and your block list may not work. It is best to not force quit the app to ensure the app works properly. This is usually what happens when a blocked call rings through.
Incoming calls are looked up on a database of numbers downloaded and cached on the iPhone in order to block. We are not able to include every suspected number in the downloaded list. Any number you manually block will also be on this downloaded database.
The key thing is that anytime you make a change or removal to the block list an update will have to happen.
The app will usually update automatically as long as you don't close the app. However, the iPhone does close apps on its own after a period of inactivity. It is usually good to open the app every 24 hours to ensure the update happens.
The fail-safe: Consider the fail-safe the app version of calling IT Support and them asking if you restarted your computer.
However, it’s important to note that when you uninstall the app, you will lose the numbers in your blocklist. I would suggest writing down the numbers in your blocklist or taking a screenshot before doing this step. With that said, use this as a last resort if you have an extensive blocklist and don't want to write them down or take a screenshot. (“Save Blocklist” functionality is a popular request and we are looking into it for future updates).
- Disable Hiya in Settings
- Force-quit Settings
- Uninstall Hiya
- Restart your device
- Reinstall Hiya
If you are a Premium subscriber you will need to go to the Premium tab. Then scroll down and tap on the option to "restore purchases" after you reinstall. This should bring the Premium subscription back into the app.
