What is it like to interact with your portfolio companies as a VC GP, specifically w/r/t other VC investors?

How you interact with your portfolio company is pretty straightforward if you're a buyout fund, but you know, if you're a VC and you're helping support your portco, what if the portco is getting conflicting advice / direction from investors? Say you have two VCs that both have 25% stake and are giving conflicting prerogatives / advice, what do you do? How does co-investing in a VC target work? What about when you prep for sale? How much do you actually interact with the other VCs who have also invested in your portco? Is this different if one of the VCs is the lead investor? Is lead investor always determined by % equity stake?

Thanks so much. I know my questions are all over the place but the direction would be useful. No need to answer them all, as I think they collectively paint the picture of what I'm trying to get at.
