I have a SharePoint list with a column of a type people group.
I have created a form on power apps that's linked with the column above but doesn't display the list of users at all.
I have to type in the DisplayName or email of a user for it to be populated.
Not sure this is the right forum for this question (CDS is separate from SP lists)... but to help you better can you post what control type you have on your form to represent the list (ie, drop down, or combobox... or just to make sure you aren't using a text input control)? Then paste the formulas from the relevant fields...
It's a Combobox:
Items : Choices('Sp list name'.column name) /*people or group type*/.
I need Office 365 users to be displayed when I click on the drop-down list.
