Our ArcGIS Online site is set up to allow SSL only security. I can't preview a private site if it is set up this way. I turned it off and was able to preview my site.
Is this a known issue or a possible bug? Where do you track all current issues?
It still isn't working for me. It actually has never worked even before all the new updates. It still takes me back to the arcgis open portal main page. It only works if I disable SSL only security.
