I have an AGOL public account. I made a web map and made an instant app. Then I selected it to share it with everyone, make it public. I also update the web map to public and everything seems correct. From my PC I can see the application well without having to log in to my account. But if I enter from another PC with the URL it cannot be seen and the message "Error. Unable to load -web map name-" appears. I did another very simple experiment and the same thing happened.
What could happen?
Thanks
Gus
