I got 2 Javascript API (Version 4.27.6) apps that use oAuth2 authentication with a portal for ArcGIS 10.9.1 Portal.
I would like to log in to the first application and start the second application (in another tab) from the first app. I expect that I don't have to enter my credentials to the second application again but have to click a "Accept" button.
I tested the apps with 2 different portal installations. With the first app it doesn´t work, with the second not.
What should I investigate more closely? Any Ideas?
Thanks!
