I don’t know how I missed this, but I found out that there is a reflector.service and a reflector.timer service that should both be enabled and started. My understanding is that if you enable and start the reflector.timer service, that it will trigger the reflector.service to update the mirror list. I wanted to make sure I was covered either way and enabled and started them both. The commands are below to do this.
sudo systemctl enable --now reflector.service
sudo systemctl enable --now reflector.timer
