Hello,
We have WAB Developer Edition on our local GIS server with a couple apps currently deployed. Our internal GIS server has a trusted CA wildcard cert. (RapidSSL)
I recently turned on the "HTTPS Only" setting in our ArcGIS Online for organizations account. But, since we turned on the ArcGIS Online setting of "HTTPS Only" , which stores the web maps used in WAB, I receive a certificate error? When I attempt to continue to website, it shows my ArcGIS Online organization URL (with https://myago.maps.arcgis.com but then redirects me to the same page after signing-in. I am no longer able to reach my app page.

I have seen a couple threads related to this issue, do I need to complete these steps?

My registered app URL in ArcGIS Online is http:// but has registered redirect URLs containing the https versions of the URL.
