Blue line on iPad Pro screen

Take it back and make the store make it right. That’s not normal. (I am presuming that blue line is on everything, meaning you see it on the main screen or inside an app,)

Apple stores have a 14 day return policy.

Try going to Settings> Accessibility> Switch Control and make sure it's turned off.

Had mine IPad Pro 12.9” about 2 months and this same problem started. A second line flashed in momentarily as well. I shut down and restarted and it did not rectify the issue. This is obviously not unique to me and to spend as much as I did and have this happy and so quickly is more than irritating. The accessibility idea below is not related. Open to other ideas as I’d prefer not to relinquish control over it to iCare or the Apple Store.

Thanks in advance.
