We have a web app builder application installed on our local web server.
We have noticed that it does not work in IE 11 on a Windows 8.1 machine. However, it does work on Chrome on a Windows 8.1 machine.
It seems to hang up over logging in to ArcGIS Online to get the WebMap.
Has anyone seen this happen?
I know IE has issues with trying to be logged into GeoNet/MyEsri and ArcGIS Online, at the same time, if your accounts are different. For example, my global (geonet/myesri) does not have access to my AGOL enterprise account. For the AGOL, I have the First.lastname_companyname. I keep these separate on purpose so that is is easier to separate/update users on AGOL as the come and go. That is my reasoning.
Anyway, that may be the issue.
