Foundation damage claim in Texas - they say its settling not covered damage

My house has significant foundation cracks. Doors won't close right, cracks in walls, the whole thing.

Filed a claim and insurance says its "normal settling" and not covered. But my neighbor had similar damage from the same soil conditions and HIS insurance paid out.

We've had drought conditions here for years. Isn't that a covered event?

Anyone in Texas dealt with foundation claims? I feel like I'm getting the runaround.
