Discord is a chat apps on Android and IOS.  Kids can also access web version of Discord at discord.com.  My kid spends a lot of time on it and I am trying to control it by adding it to Parental Controls. I added discord.com into "Filtered content/Apps and websites" (discord cannot be recognized as apps in Deco apps), but it doesn't work.  My kid keeps chat on it.  I believe I set it correctly since Youtube and youtube.com are working well.
