Issue with offline forms

Question

I'm having an issue with offline forms. When I test on my mobile device, I fill out all the information and click submit to queue it, but when I go back online it won't auto-submit. I keep getting the message that the form has changed (although I haven't made any changes). Are there other reasons why I would see this? I removed all validation messages and there is no dynamic behavior. Thanks!

Thank you for your responses, but I figured out the problem. The answer to both of your questions is "yes". The issue was that I was trying to default a field to current date/time then store it to a variable when submitting the form. Once I removed that code the auto-submit worked.
