Odd multicast problem


Ive noticed recently that for some reason my cellphone battery was getting drained alot when on wifi and when tracing the problem it led me to the epic games launcher and the editor itself spamming multicast over my network
and by it my phone always downloading data or getting pinged.

Now it seems my router is **** and doesnt apply settings to disable multicast and leads me to firewalling the editor and the launcher.
The only drawback is i cant login over the launcher anymore if i block the multicast.

Fortunately i can still work without it having net access.
