We have a form that has been working in Nintex Mobile (on SharePoint Online list), and now all of the sudden, no user can open the form and they are presented with an error "String was not recognized as a valid DateTime (<a long guid of characters>)"
This was a working form, that just seems to have stopped working all the sudden. No changes to the sharepoint list / or to the actual form itself.
Has anyone seen anything like this before?
