Blocking specific app from mobile data only

I’m a new user on my 7 day trial. I am looking for an Android firewall or similar that will let me block a specific app (Plex) from using mobile data, but let it use wifi.

I have the Plex app set up to use “synced” downloads, but for whatever reason, it kept streaming the files every time I played them. I want to stop this from ever happening again, since it used like 14 GB in two months (at $12 a GB this adds up).

Is there any way to configure what I’m after?

Hi @captain,

Apps blocked using the firewall will not connect to either wifi or mobile data. There is no way to allow one but not the other using GlassWire.
