I am not able to set the time of a date with time field on the mobile app.
My example is creating a Task and setting the Due Date. Tapping the time drop down does nothing. Tapping the time next to the date makes the dialog all grey (in dark mode). See screen recording for demo. You can’t see where I tap, but first I try tapping the time drop down both on the arrow and on 00:00, then I try tapping the 00:00 next to 2026 and that’s when the whole dialog just does dark.
