Sync speed over internet slowed down by setting internet upload speed

I recently changed some settings on my Plex server. My internet upload speed is ~6Mbps, so in my server i setup the remote access screen “Internet Upload Speed” to 6Mbps.

Streaming works perfectly fine and will use the 6Mbps but when trying to do a mobile sync it only uses about .7Mbps. If i remove the setting and leave it blank the sync will boost up to 6Mbps right away.

Is there an issue with this setting or it there something i’m doing wrong?

Thanks,
Justin

Anyone else experiencing this?
