Please be so kind as to read my full post before responding.
Thank you for your consideration.
As a preparation for a PowerApps workshop, I (re)did the current "App in a Day lab" excercises.

In lesson 2
PAHandsOnLabContent\02-Common Data Service for Apps Lab Manual.pdf
I noticed that the default, standard, unmodified, Display Form for a CDS DateOnly field still shows a time as well, and the data type seems to DateTime.
The result looks like this, including a time:

As far as I understand, according to the course pdf, I should be getting a pure date field instead:

The field is set up as DateOnly

The used display form is, as mentioned, unmodified, with data cards still locked

My question:
- How do I get the Data Card for Request Date to only show the Date?
- In particular: Do I have to unlock the data card to deviate from the default to show only the date for a DateOnly field?
