Hi Team, should I set up tRoas for my pmax campaign? It have been running for 5 months. Settle around 250% actual roas. Whenever I try to set up tRoas, my campaign actual roas dropped below 100% roas, I do normally set up tRoas around the actual roas of 3 weeks data. I want to push my campaign to 300% roas, how can I set up tRoas that I can achieve that target roas ? What sort of data period that i should look at? Is there any other setting in Pmax that I should do to improve the result of my pmax? Thank you team
