I have moved a gallery from the now deprecated public gallery app, to the now supported Minimal Gallery.
But I am having trouble getting all items showing up in the app, when logged out.
The group I use is here:
https://www.arcgis.com/home/group.html?id=3078222259324ec09bc5ba18455ae812#overview (all items publicly shared from different Swedish users.)
But in the gallery, only 13 items show up (as not logged in) and all items are Document links from my own portal.
But a logged in user will see all items in the gallery, as expected.
Is there a bug preventing content from other portals to show up in the gallery app for anonymous users?
I am experiencing the same, or a similar, issue.
