This question may sound like a personal preference question, but recently my colleague ran into an issue with Edit Widget. We couldn't get the Edit widget to work out of the blue. The web app was designed on Edge including all the widgets needed. It was functioning just fine before we left it alone. After several weeks of letting users know that we were ready to deploy a new web app, my colleague noticed that the Edit widget became blank for no reason. There has not been any reconfiguration took place on the web app between when we last left off and when we were about to launch to the user.
The layer remains editable in web map but as soon as it is in an App form, editing isn't functioning as it normally should. We test on other editable layers, too and notice similar issue occurred on previously designed web app. The Edit widget isn't functioning for both the author and user. It just spins as if it is trying to do something. We never had the patience to let it sit there for more than 5 minutes.
A case has been submitted but not sure if this a common theme to the user community. Like many orgs that deploys office 365, Edge by default is our IT's preferred browser. Asking user to use web app in Chrome goes against our IT's preference. In addition, with IE gone, and Edge is chromium based, I would think this preference would become a thing of the past.
