Datetime-local problems iOS

I am using an oh-input card in a widget with the type: datetime-local. This works nicely from a PC using Chrome browser, but doesn’t display a date/time picker in iOS.
I read in the comments on rlkoshak’s DateTime stand-alone widget that with the next milestone you would be able to use datepicker as a type which would be consistent across browsers. I have updated to 4.0.0.M1, but I’m still having the same problem.
Are there any updates on this or workarounds?
