I have a PowerApp with a SharePoint list as the data source. In that list there are a handful of "People or Group" columns which require the user to select someone within the company who will fulfill that role on the project.
When creating a new entry, I don't run into any issues searching any of those fields and selecting a user. However, when editing an existing entry, the form often doesn't return anything - you can type in someone's name, and no suggestions will appear, which prevents you from selecting a valid user. The app doesn't do this for every person field; some of them will return search results, and others will remain blank, and it varies which ones are working each time I test it.
As a side note - I also have this issue on a couple of choice fields. These fields just list a handful of choices, but if someone wants to change the original choice in the Edit form, the full list of choices does not appear.
I have a command to Refresh('Data Source') for the screen OnVisible property, but that doesn't seem to have really made a difference.
Is there anything else I can try to get these fields working?
