Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

  1. Create a horizontal scrollview and attempt to use content inset and content offset. Nothing will happen

Expected Results

Describe what you expected to happen.

I would expect the same results as iOS with contentInset is moves the start and contentOffset is moves the initial starting value
