When adding a web map containing a secure layer into the map widget in ArcGIS Experience Builder, the sign-in pop-up appears in the background, causing it to load infinitely.

Workaround

There are two possible workarounds:

Workaround 1:

Once the web map is selected and it starts loading, close the 'Add New Data' window. The sign-in pop-up then appears. Sign in, then open the 'Add New Data' again to choose the web map.

Workaround 2:

Add the secured layer to the portal and store the credentials. A web map consisting of a secured layer with stored credentials does not face this issue.
