I have an app that is set up to write data back to a SharePoint list using a form control. It has been working perfectly for months.
Today, it no longer writes back to the SharePoint list after the button with SubmitForm OnSelect set up is clicked - but only certain fields (not all fields) are impacted. There is no error message, it simply doesn't save. The fields are all Choice fields in the SharePoint list, but other Choice fields work fine.
None of my fields are mandatory, which was an issue that I've seen come up in other posts, so I don't think that's the problem.
I'm not sure how to troubleshoot for this and would appreciate any suggestions.
