I have a custom form I created from a SharePoint list (Integrate, PowerApps, Customize Form). It was working fine for several months. All of a sudden one of fields is not populating in the SharePoint list. It is a choice column, dropdown. The choices show up in the form but when the form is saved, the column does not populate in the SharePoint list. I have made no changes to the form or to the list. I am completely baffled. When it stopped working, I removed the field and added it back to the form. It is still doing the same thing.
Does anyone have any suggestions for me to try? Or anywhere I can look to see why this stopped working? TYIA
