I keep getting this pop up that say load.biz ??? What does this mean and how can I stop it?

It sounds like you might be experiencing pop-up ads or notifications on your iPhone. Here are some steps you can take to try to get rid of them:

1. If the pop-ups are occurring while using Safari, close all browser tabs. Sometimes, these pop-ups are triggered by certain websites.
2. Open Settings > Safari > Clear History and Website Data. This removes browsing history, cookies, and other browsing data that might be causing the pop-ups.
3. In Safari settings, ensure that the "Block Pop-ups" option is enabled to prevent pop-ups from appearing while browsing.
4. Consider installing reputable ad-blocking apps from the App Store. These apps can help prevent unwanted pop-ups and ads from appearing in Safari.
5. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
6. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
7. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
