Sort by new type date field on mobile

I had my tasks in a project sorted descending by a Start Date text field where I would manually type in the date. Since the new calendar date field came out, I’ve just been adding start date to the new field I created (which didn’t allow editing earlier on mobile but is now working) and not double entering into that text field. I transposed all the text dates to the calendar date field when it was first released but now I can’t sort by that new calendar date field. Is there a way to do this or is this in the pipeline for app feature?
