Cast Iron Help

I had a well seasoned cast iron skillet and would oil after each use then heat it up.

I had some seasoning stick to it recently and scrubbed it with a chain mail scrubber.

Now when I put oil on the skillet, it’s not spreading out across the entire skillet, it’s almost as if the pan is either absorbing it or repelling it, but it evaporates immediately. (Skillet is at room temp when it does this)
