Estimated Download time and cap download speed

I know you only have like 15 games in the store. But please give me some of the essentials. If i download 90gb for warzone Id like to play something else with a friend, this is hardly possible because there is no way to just cap the download speed.

You can throttle your download speed in the settings. Click the blizzard icon in the top left -> settings

I tried that. It doesnt seem to affect anything tho.
