Seems to be a problem of an too old Sabre dependency. Someone opened a issue over at Sabre but they don't see the problem there: https://github.com/sabre-io/dav/issues/986

Well, that error message is pretty clear: The value type (DATE or DATE-TIME) must be identical for DUE and DTSTART

From RFC 5545 Section 3.8.2.3:

This property defines the date and time before which a
      to-do is expected to be completed.  For cases where this property
      is specified in a "VTODO" calendar component that also specifies a
      "DTSTART" property, the value type of this property MUST be the
      same as the "DTSTART" property, and the value of this property
      MUST be later in time than the value of the "DTSTART" property.
      Furthermore, this property MUST be specified as a date with local
      time if and only if the "DTSTART" property is also specified as a
      date with local time.

So this is definitely a bug in the 2DO App not following RFC 5545 properly. => Please report the issue to the 2DO app developers

Thanks! I just changed to another DAV app... they want 29€ for that broken implementation. Standard impl works fine now.
