I haven't had this issue before until now. I have multiple dynaforms, including 1 called "Summary". In the Summary dynaform, I have a multiple file upload control. However, any files that are uploaded to it, isn't accessible by anybody. In the Process Permissions, I added everybody and all groups (for testing purposes) and that didn't work. I made sure the permissions were set for NO for participated. However, when set the Summary setting to point to a dynaform that's used in the flow, the attachments show up. So I cloned the dynaform that work, and renamed it Summary and tried it, and it failed. That let me to suspect that the attachments were only showing up if it actually appears in the flow. So I added Summary as a step and viola, it works.
This doesn't make sense to me since I have done this correctly in other processes as well. What could I be missing?
Please see my attachment for the process.
