Delay when live-streaming from Zoom to Youtube

My internet speed is fine per www.speedtest.net, but I still have a 15 second delay between Zoom and Youtube when I try to Livestream. I've learned which variables to change on the youtube end as far as latency and buffering, but I still have lag. Has anyone else had this issue? Do you just ignore it and go along with things, checking in on the live stream chat in a proportionally laggy way?
