This is actually working as expected, but you have to call `iter` not `next`:
```python
>>> a = pa.array([4, 5, 6, None])
>>> iter(a)
<_cython_3_2_4.generator at 0x7c78bd2ea200>
>>> list(a)
[<pyarrow.Int64Scalar: 4>,
<pyarrow.Int64Scalar: 5>,
<pyarrow.Int64Scalar: 6>,
<pyarrow.Int64Scalar: None>]
>>> iter(pa.chunked_array([a, a]))
<_cython_3_2_4.generator at 0x7c78bd2e9ee0>
>>> list(pa.chunked_array([a, a]))
[<pyarrow.Int64Scalar: 4>,
<pyarrow.Int64Scalar: 5>,
<pyarrow.Int64Scalar: 6>,
<pyarrow.Int64Scalar: None>,
<pyarrow.Int64Scalar: 4>,
<pyarrow.Int64Scalar: 5>,
<pyarrow.Int64Scalar: 6>,
<pyarrow.Int64Scalar: None>]
```
