Trackpad still works, can click in other areas but the bottom right hand corner of the trackpad is always below the lip of the case. Gestures also work, so I don’t believe the glass is broken. Any ideas? It’s driving me nuts. I’ve tried cleaning around the corner with a small nylon brush, no luck.

You might try some computer duster, one that includes a solvent. If that doesn’t work you will have to open the case and see if anything is jamming it from the inside.
