We have a Survey created from ArcGIS Server feature service. As more inspectors start entering data we are noticing that some surveys with multiple attachments are getting corrupted when trying to submit. A survey may have 6 photos, the submit will get to attachment 4 then hang. Once this happens we can't get back into the survey or submit it again. Cell coverage may be an issue in some cases but wanted to see if anyone had come across similar issues.
