Good afternoon. I am unable to log into Survey123 (version 3.9.149), on iOS 13.6, using a federated enterprise login after logging out of AGOL. I get as far as filling out the URL of our organization; however, when I arrive at the screen with “Sign in to (org name) with (org name blue button)” nothing happens aside from the button showing a blue halo around itself. The same behavior occurs if I try to log in via a valid ArcGIS Login. If I try to replicate it using Collector, I am able to access the login screen and log in properly. I am unable to replicate the issue on Android, nor on the Survey123 website as both exhibit the correct behavior. I have other users having the same issue, especially when they were able to use the service, but logging out and attempting to log back in to AGOL fails. We are able to log into Portal, which is also using federated logins, on Survey123 without issue.
Thank you,
Darren
