I have a team in the field trying to submit surveys with photo attachments. Several of the surveys are generating a red exclamation point when they try to submit (see attached image). They can no longer be opened once that occurs. Also, for the surveys that are able to upload, many of the photos don't appear to be attached. It appears that the photos that were attached to uploaded surveys are also no longer stored in the attachments folder on the android device they are using. The only photos they can see in that folder are the ones they haven't yet submitted. Can anyone tell me where these photos might be and how to stop them from deleting or disappearing? Also, why do some surveys appear to be having difficulty uploading.
