Hi there. Want to share existing crowdsource polling apps within my Hub and am experiencing inconsistent behavior depending on how the app is exposed:
Application Card with Classic Story Map: OK

App shared as a link within Text Card and opening in a new browser tab: OK

App shared using an App or Iframe Card: NOT OK
App shared using a Gallery Card: NOT OK
Our preference is to use a Gallery Card or an App Card to share the apps:

Therefore, it would be helpful to understand why in these "use cases" receive the following...
You are currently signed in as: 'xyz'. You do not have access to this resource: public proxy layer
Thank you!
PS: Understand that the url above is referencing the public/proxy layer as described in the article below...

Public/proxy layer is shared with Everyone and as noted does not cause a problem in the first two "use case" scenarios.
