We have a portal set up for our company with a custom themed web app. Last week one of the employees complained that he could not access any feature popups on the webapp.
This week the same happened to me. I cannot use the coordinate widget, no popups are loading, and I cannot use measurement tools. Seems like all onclick content broke for Google Chrome.
Clearing cache, changing users or restarting the server doesn't do anything. There are no strange error logs.
All of this content is also working just fine on Firefox and Microsoft Edge. Really seems to be a sudden Chrome thing but I dont know how to fix it.
Also found this post from about 2 weeks ago detailing the same issue: https://community.esri.com/t5/arcgis-web-appbuilder-questions/custom-web-app-not-working-in-chrome/t...
