Remarketing Code "waiting for" Slows Site Speed


I’ve tried to do as much searching as possible but cannot find any information on this. The twitter custom audience code is constantly slowing my site down, indicating that it is “waiting for” Is there a way to bypass this redirection so as to improve site speed?

Even including it in Google Tag Manager does not improve site speed. Alas, my only option is to remove Twitter remarketing from my site and marketing plans entirely, unless there is something I can do to avoid this significant lag?

Any info/tips welcome… Thanks
