Experimental Webkit features

quentinjones1,

Thanks for the info. We found this resource about Experimental Webkit Features: About Accessibility Events - Apple Support

These settings are meant for developers to tweak their apps to work with Accessibility features. It would be difficult to say what those were set at prior on your device.

You could try following the steps here to Return iPhone settings to their defaults.

Keep in mind "If you want to save your settings, back up 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."

Take care.

If you want to know what are enabled by default Experimental Features for Safari see comment from SravanKrA: https://discussions.apple.com/thread/252473904
