InfoPath Dev

Hi, i have infopath travel request with sharepoint designer workflow (2013). We are on Office 365 A2. I have discovered that when i save a form as a draft, can't be opened again. that worked for a while, i haven't change anything in form or workflow, it should just save a draft and if a person want to continue filling that request it should be available for that. i sow that some update was going on on infopath online (i am global admin on office 365) so is that somehow connected, do you have any advice what should i do? best regards, SD

I guess I would try to reproduce with a test form. I'm not sure what you mean by "save as draft" - is this some functionality you've added to the form? A library submit connection? Just using the Save button in the ribbon?
