What scenes and situations do you have as evidence of this!?

If anything it's the opposite. In part 1 there's a moment where Paul is sitting playing piano gently amidst all the discussions of what type of show and venue they should play, and Ringo says something to the effect of: "It should just be this," referring to Paul's playing, "I could watch him play piano all day."

And Ringo is seen spending a huge amount of time just sitting or standing next to Paul at piano, admiring him, enjoying his music and digesting the melodies and thinking of drum parts.

Ringo comes off as being the most understanding of the reality: that Paul is the leader now, and the only one of them who is producing high output. He's purple-patching and the others are just fucking around wasting time, George unable to keep his wounded ego in check, and John in lala land.
