I am having problems with ArcGIS Online web app that I embedded on a password protected web page built in Weebly. This app has a group filtering widget and several types of layers in including a point layer with about 2000 seed collections and polygon layer with about 1000 plant occurrences. This app functions as expected when viewed on google chrome (Version 60.0.3112.90) However, when using Safari (Version 10.1.2 ) the base map appears with no layers or widgets, and when using Firefox (Version 54.0.1) the basemap appears for a few seconds then disappears. I tested deploying the app on a non-password protected page, and had the same issue. Has anyone else experienced differences in app deployment between browsers?
