Hi,
You can try this: on your iPad, open Settings > Safari (or Edge, if you’re using it), then look for AutoFill or Passwords and Autofill, and toggle off all options such as "Use Contact Info," "Credit Cards," or "Save Passwords." Next, go to Settings > General > Keyboard and turn off Predictive, Auto-Correction, and Shortcuts, these also trigger that gray autofill bar above the keyboard. Once done, restart your iPad to make sure the changes take effect. Just curious, does the bar still appear even when you’re not using Safari or Edge, like when typing in Notes or Mail? And have you noticed if it happens more with form fields or password boxes specifically?
Kind regards,
