Best Tips & Tricks to Fix Yahoo Not Working on iPhone
From letting you fix the sluggish internet connection to cleaning up the ill-functioning app to ensuring the smooth background app refresh, this guide consists of a variety of solutions to get rid of the problem.
1. Check Your Internet Connection
Yahoo services require a stable internet connection, and poor Wi-Fi or cellular data can cause them to fail. Make sure your iPhone is connected to a strong and stable internet connection.
- Try switching between Wi-Fi and mobile data to see if Yahoo starts working. You can also enable Airplane Mode for a few seconds and disable it to reset the network.
- Should your Wi-Fi continue to malfunction, forget the Wi-Fi network and reconnect to it.

2. Restart Your iPhone
A quick restart can fix temporary glitches affecting the Yahoo Search app.
- To do so, hold the Power and Volume Down buttons (or just the Power button, depending on your model), then slide to power off.
- Wait a few seconds and power it back on. Try opening Yahoo again after the reboot.

3. Update the Yahoo Mail App
Outdated app versions may be incompatible with the latest iOS updates or contain unresolved bugs.
- Open the App Store, tap your profile icon, and scroll to see available updates. If Yahoo Mail is listed, tap Update next to it.

4. Remove and Re-add Yahoo Account
Incorrect or corrupted account settings can prevent Yahoo from syncing properly.
- On your device, launch the Settings app > Apps > Mail > Accounts > Yahoo, then tap Delete Account.
- After that, return to Accounts > Add Account > Yahoo, and re-enter your login credentials to add it back.
5. Enable Background App Refresh
If disabled, Yahoo Mail won’t update in the background, leading to delays in receiving emails.
- Navigate to Settings > General > Background App Refresh and ensure it’s turned on for both Wi-Fi & Mobile Data and Yahoo Mail.

6. Check App Permissions
If Yahoo doesn’t have access to mobile data or notifications, it might not function properly.
- Head over to the Settings > Yahoo Mail and ensure permissions like Mobile Data and Notifications are enabled.
7. Reset Network Settings
Network issues can affect app connectivity, especially with mail syncing.
- Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- This will remove all saved Wi-Fi networks and Bluetooth pairings, so reconnect afterward.

8. Enable Less Secure Apps in Yahoo Settings
When using Apple’s Mail app, Yahoo may block access if it detects the client as “less secure.”
- Sign in to Yahoo via a browser, go to Account Security, and enable Allow apps that use less secure sign-in.
- This setting may not be available for accounts with two-step verification enabled.
9. Check for iOS Updates
Bugs in the current iOS version might be making life difficult for Yahoo and preventing it from functioning properly.
- On your iPhone, head over to Settings > General > Software Update and install any available updates to ensure your system is up-to-date and compatible with the Yahoo app.

10. Delete and Reinstall Yahoo Mail App
No luck as yet? Now is the right time to declutter Yahoo. Reinstalling the app ensures you get a fresh, bug-free version.
- Tap and hold the Yahoo Mail icon, choose Remove App, then go to the App Store and reinstall it.
- Sign in again and check if the issue is resolved.
