Hi all,
I have a test canvas app with one screen containg a form and a combobox.
Both are based on a SP list made of two columns:
Title and user. The user column is of type People

I didn't change anything in the form property. I left them to the values set when creating it. In the combobox I've set the value for Items property.
The form combo is a modern control, the combobox outside the form is a classic control.
The test list is manualy populated with just one record
The problem is that only some users are showed, let me say, a little bit more than 10. In my tenant I have more than 60 users.
