Funamo other browser block
I just recently became aware of this as well. Neither the browser "DuckDuckGo Search & Stories" is blocked by Funamo, nor are the searches and webpages blocked once inside the app.
Additionally, even if that app is marked as "protected," it can still be bypassed if the app is uninstalled and reinstalled.
If there is a browser embedded inside another app, you will need to protect the app to block it.
To prevent user from uninstalling and reinstalling app, you can enable Application Quarantine feature. Once it is enabled, all newly installed app will be automatically blocked.
