I have a form that is used to edit or create items in a Sharepoint list. It has 2 dropdowns that contain static lists of options, and several text input boxes and 2 date input boxes.
The problem I have is that when I open the PowerApp and select an existing item to edit, all the values saved in the Sharepoint list are showing in the form, except for the 2 dropdowns, which are blank.
If I cancel this and then select another item to edit, the dropdowns are poulated correctly. Even if I select the same item that originally had the problem, it now works fine. So it seems the first time the form goes to Edit mode, it fails to load the dropdown values (that were saved last time).
Please could someone advise how I can fix this? I have tried adding various things to my Edit button, such as ResetForm(InputData), but to no avail. Also, when I run the app in preview mode from the app editor in the browser, it works fine. I am using Internet Explorer.
