Help setting up google optimize through GTM
I was implementing Google optimize using GTM, as in my ecosystem GTM handles UA, so wanted to implement optimize through GTM too. The problem which I am facing is a white screen which is there for almost 4-5 seconds, a very bad user experience.
Is there a way around to avoid this delay.
I also tried putting Optimize scripts in the header but that is causing an issue "same web property ID is tracked twice" since I am using the same GA id in optimize script which is already used in GTM.
Can anyone please help me on this.
Thanks in Advance,
