We have an application that is running on version 4.9 of the API. It utilizes the BasemapGallery widget, which includes a WMTS service hosted by EagleView/Pictometry.
The application will not load in Edge following Microsoft's recent major update, and it gives the following error in the console. Is anyone else experiencing this issue and if so, is there a workaround?
HTTP503: SERVICE UNAVAILABLE - The service is temporarily overloaded. GET - https://js.arcgis.com/4.9/esri/widgets/BasemapGallery/support/LocalBasemapsSource.js
Error: scriptError
