I am working on a Cordova Application for Android and iOS devices and I want to integrate accessibility into the application. I am having an issue with the focus border. When TalkBack is on for Android devices, the voice assistant recognizes the buttons and reads them to the users. However, there is no focus border appearing highlighting the item. On iOS devices, it works as expected and there is a focus border appears when an item receive the focus.
Does anyone have an idea of what might cause this issue? I am using Cordova with Jquery UI for development.
