ADM (Advanced Download Manager) is not grabbing links automatically

In my previous Android phone, when I to copied any link, there was a popup window of ADM asking whether I wanted to download the specific file or not. It required that ADM should be running in the background. But now, there's no such pop-up. I've to manually paste links. Although I've enabled the pop-up permission of the app in phone settings. Is there some other android permission, or ADM setting that I'm missing? EDIT : I've also checked for auto intercept links, I've enabled it. Still not working.
