One of our users is using collector on his iPhone. He is loading Apps we have created that allow all of our users to add data using the "+" symbol. All users , who all use the iPhones, are having no issues and are seeing and using the "+" symbol to collect data. We have asked him to Log out and back in again. The system is recognizing him logging in. He has uninstalled Collector and re-installed to no avail. Before we reset the account does anyone have any suggestions?
