I created a survey last year and used it in the field, as did a number of other folks. Worked great and I got a lot of data collected. I made a few improvements in anticipation of the coming field season and sent it out, but I'm hearing that people are being asked to sign in to submit surveys. I was just outside and tried a test survey, but now I'm being asked to sign in also. at the top of the collaborate tab under "Choose who can submit data to this survey:", Everyone (Public) is checked. I've been trying to figure out what other setting could have gotten changed. The feature layer the surveys feed are also shared with everyone. I've dug around in the settings and, as far as I can tell, nothing's amiss, although what some of the correct settings are aren't entirely clear to me. I'm getting a bit exasperated. Anyone have suggestions?
