I still can’t get my iPad to rotate screen

Have you disabled Screen Rotation in the Control Centre? Drag you finger downwards from the top-right corner of your iPad screen to reveal the Control Centre. Tap the Rotation Lock icon to lock/unlock.

Do you have the orientation lock on?

From the top right hand corner of your iPad, swipe down to open Control Center.

Look for an icon with a lock in it and an semi circle arrow. Is it red? If it is, tap it to unlock screen rotation.

Note: Not all apps rotate. If your issue is with a 3rd party app, it likely was not coded to rotate. Even if your screen can rotate, and app not coded to rotate won't rotate.
