How do I add a survey thumbnail in Connect? I can preview it under the settings - general tab but when I publish the survey it goes back to the default.
What version of survey123 Connect you are using? And where are you seeing the default thumbnail with your survey?
After publishing the survey, the thumbnail should be seen from the field app download page, or the content page in Survey123 Connect(My Survey Designs) page. You will have to download the survey again to see the update thumbnail though (click the circle icon on the upper right coner of the survey).
Its version 3.5.166. This is the view before adding thumbnail
This is the preview with thumbnail before publication.
This is the overview after publication in Connect. And obviously there is no thumbnail when it is downloaded to the phone.
I tried v.3.5.166 but could not repro the issue. I was able to see the thumbnail image after re-publish the survey. What image type/file size did you use to set your thumbnail?
Its only 117 kb. I've noticed that the download icon is constantly on for this survey in Connect and doesn't go off if I download again to the PC (see image above) . Maybe that is related to the issue.
Are you using AGO or Portal/Enterprise, if so what version?
Based on the AGO documentation for item thumbnails here is the recommended details:
Images must be in PNG, GIF, JPEG, or BMP format; the image file will be converted to JPEG format before it is stored within the item's metadata. The recommended image size is 200 pixels wide by 133 pixels high.
Another thing to note is the image name and extension should be all lowercase (ie. myimage.jpg). We have seen issues before where uppercase or special characters in the name or extension can cause issues in Connect and the field app.
Does the issue happen with other surveys you have with the same account?
I'd suggest to contact Tech Support to log an issue so that they can troubleshoot it with you to narrow down the actual problem.
