I have a Silverlight 5 app hosted in SharePoint Online, which asks the users 72 questions and right at the end writes their answers to some SharePoint lists.
When I trialled it with 8 users, the first four to finish had their results save to the list fine. The last four to finish didn't get their results saved.
All users had CONTRIBUTE access to the site in question.
I am thinking that somehow, the apps access to SharePoint via the Client Object model has timed out with the users who took longer to complete the test. Is this likely?
If that is the problem, are there any known solutions?
