How do users update a public survey that they've already downloaded onto their device without signing into ArcGIS Online? Is there a way to force a download of a new survey version via the URL?
Unfortunately, the only way currently is to have them delete and re download the survey. We do want to bring in automatic detection of updates / automatic downloads as a feature, but don't have a timeline on that. I'm placing this conversation into the enhancement issue as in the public survey case it is needed for updating (as opposed to being able to select it from the download list).
Just letting you know we have been working on public survey update notifications in the latest Survey123 RC builds available on the Early Adopter Community (EAC). The new feature will now alert the user in the field app when an updated survey is available, a notification banner will be displayed at the top of the gallery page, as well as a new update surveys page to bulk download update surveys and the user will also be alerted when trying to open a survey that has an update. This enables the user to do an update of the survey before proceeding to collect a new survey record.
Please test out the latest 3.9 RC2 builds and provide any feedback via the EAC user forums for this new feature. You can find the 3.9 RC2 announcement with details on EAC.
