Dark grey bar at the bottom of Chrome in iPad The grey bar in Chrome in the image above in iPad OS blocks form fields at the bottom of the screen. I believe it is the auto fill feature Chrome has. I know it is not the shortcuts bar and also predictive text is off.

Is it possible to get rid of this bar to get more space on screen?
You cannot remove that grey bar because it's an area of the virtual toolbar with additional tools that  will appear like Undo/Redo, Cut, Copy, and Paste. The "up and down arrows" is like hitting Tab and ShiftTab to cycle between fields on the webpage.  It usually doesn't show unless there are fields to navigate or items in the clipboard.

It appears in Firefox, Safari and Brave browsers as well.
