Hi, I have just started to get this error intermittently on an App that previously has been working fine.
There was a problem saving your changes. The data source may be invalid.
code is :
Set(Loading,true);SubmitForm(Form1);Refresh(PDP);ResetForm(Form1);Set(Loading,false)
it happens when submitting a form to SharePoint - it doesn't always happen and sometimes the error shows up once but then saves absolutely fine after repressing the button.
Anyone any ideas whats suddenly making this happen?
