Switching from ROAS bid strategy
I have a problem in one of my campaigns switching from a ROAS bid strategy to conversion optimizer.
Although I believe I´ve done all necessary changes, even deleting the strategy, I just get the message:
"When you wanna use this strategy [conversion optimizer] you must first remove all the strategis that at present are used in your ad group."
I have switched everything to manual CPC, but I can´t get it to CO and not even eCPC.
Is this a bug?
