In one of my early apps, the method for submitting and editing data via the app were performed via SubmitForm(frmNewEntry) and EditForm(frmEditForm) formula of OnSelect. (Patch was not applied).
Now that the app is 'Live' and being utilized, users have requested to include an additional column from the SharePoint Datasource. I have added the field from the datasource and saved my changes. However, when a user enters data into the new field, on a new form via the app or the customized form, the data is not being saved back to the datasource. Interestingly, when I add a new record via the SharePoint customize form, the initial refreshed view of the SharePoint list, shows the data that was added in the new field. However, after a second or a refresh, that data 'disappears'.
Any thoughts why it it isn't picking up the new field?
