After connecting to a Portal account with my survey123 desktop application I am not able to sign into my AGO account, or any other Portal account. Each time I click the gear icon and chose a different active Portal to sign into when I return to the sing in page I am prompted to sign into the same portal (i.e. the Portal I just signed out of, not the Portal or AGO account I just set as active).
This issue began after adding our non production and production Portal connections to my S123 (version 3.6.153) desktop app in Windows 10.
The steps I go through to change my active are as follows:
I have uninstalled and reinstalled the S123 app, and deleted the folder it is installed in twice now, but every time I reinstall the app I am promoted to sign into my non prod Portal, even though the Portal connections are not listed in my active Portals. Is there a file or folder in any of the normal ArcGIS or ESRI program folders that stores credentials for the S123 desktop app that I can delete so that I can log into my AGO account?
I've tried to reproduce this based on the description you've provided with SAML test portals and am unable to. Can I ask that you file a ticket with Esri Support to further diagnose what might be at issue here?
