Hello! I don't have much experience using Power Apps and I encountered a problem.
In short, I have a form with a few fileds. One combo box where the user can search for a person from Office365Users, and another combo box, for the manager of the person selected in the previous combo box, wich is completed automatically based on the first combo box or allows for manual search.
DefaultSelectedItems property for the second combo box :
{Value: Office365Users.Manager(ComboBox1.Selected.Id).DisplayName}
Update property
ComboBox2.Selected.DisplayName
The problem is that the value of the second combo box is not sent to the SharePoint list. I don't know if I used the right approach. Any suggestions?
