However, when we try to access Web AppBuilder all we see is a grey screen. Story maps work. Experience Builder seems to be working. Has anyone else had this problem? We've checked everything we can think of and had ESRI tech support working on the problem but we haven't made any progress. Any suggestions?</P> Mon, 07 Dec 2020 18:22:43 GMT https://community.esri.com/t5/arcgis-enterprise-questions/web-appbuilder-not-working-in-new-10-8-1/m-p/1007475#M29057 JulieARediker 2020-12-07T18:22:43Z https://community.esri.com/t5/arcgis-enterprise-questions/web-appbuilder-not-working-in-new-10-8-1/m-p/1007490#M29059 <P>Hi Julie,</P><P>What do you see in the web traffic from the developer tools?</P><P>Have you tried a repair of the Portal for ArcGIS installation?</P><P>-Calvin</P> Mon, 07 Dec 2020 18:48:22 GMT https://community.esri.com/t5/arcgis-enterprise-questions/web-appbuilder-not-working-in-new-10-8-1/m-p/1007490#M29059 Anonymous User 2020-12-07T18:48:22Z
