We are developing a new Adaptive Forms application in AEM 6.4 and are seeing a javascript error reported by IE and Edge....
Object doesn't support property or method 'includes'
File: af.js, Line: 12, Column: 9
Everything works fine in other browsers, but IE and Edge throw this javascript error on radio button clicks, tabbing from one form field to another, etc. I know IE doesn't support "includes", but I'm not sure we should be going into af.js to rewrite that. Can Modernizr help us here? Any other solutions?
