I am currently receiving this message for my "Clear the Air" survey (https://survey123.arcgis.com/surveys/465311af1fb845a8a4b08b843c82e2bb/overview ) when users attempt to access it via the QR code on their smartphones. You can access the survey if you use the link generated on the Collaborate tab on a PC. This was first reported to me at 10:30 today 4/9/2019.
The data is viewable on the Survey123 website. The ArcGIS Online Health Dashboard does not report any type of general outage. The survey was created using Survey123 Connect.
Any ideas?
