Sort is disabled by updating new data.

Sort by drag and drop works for the first time.
But I am using immutable data. If I add some data to the data source, sort is no longer available.
How can I solve this issue?
Thanks

Start by reproducing drag-and-drop sorting with the initial data, then add an item through the immutable data source and compare the resulting behavior. Trace the data-update path used by the React Native sortable list. Done means sorting remains available after new data is added.
