Conversion based campaign , can fb and google data be mixed?

I am running a sales based campaign on Google and fb and I choose add to cart as objective on facebook. I am running both simultaneously. Can it create me problems , I mean can fb pixel registration conversions coming from Google (yt) ads as its own ? is it better to run one of them only? thanks

Both platforms are good, but I think the Facebook platform is still number 1 and more stable
