I have created a web map through AGOL and configured pop-ups on three of the layers. I have created an app using Web App Builder. All three layers' popups work in Chrome and Firefox, but not in IE 9. In IE 9 only two of the three popups appear. Of course it has to be the most important layer (parcels) whose popup doesn't work. Has anyone else experienced this and if so any suggestions on how to fix it?
