I'm starting a new WIP that has two POVs. I've never done this before and my biggest problem right now is switching between voices.
There's no one correct way to write. You have to find what works for you.
I can tell you what I do, but I can't even guess whether this is your right approach.
When I am in character POV i am
inside that character. I see through the character's eyes. I feel through the character's skin. I know the character's thoughts. I don't think about how the character should sound. I don't think about technique at all in this first rough draft. I'm
in the story, living the scene. I'm
hearing what the folks are saying.
This slipping inside the skin of the character does not happen the day I first conceive the guy. It takes months before I know the character well enough to get inside him. I have to be patient.
It helps, in transitioning from character to character that I'm also moving from one scene to another. I'm in a different place and time. (I don't have the technical chops to transition from one POV to the other in the middle of a scene, so I plot the story accordingly.)
residue from MC #1 sticks around in the first part of MC#2's chapters, and vice-versa.
I try to make the POV characters very different from one another.
Fr'instance, in
Spymaster's Lady the POV characters were
(1) a nineteen-year-old girl thinking in French.
(2) a twenty-seven-year-old man thinking in upper-crust English.
(3) a twenty-year-old boy thinking in Cockney.
(4) a fifty-year-old genius.
(5) Omniscient Narrator.
None of these folks is going to sound like any other.
Not saying this is the case . . . but could your problem arise because your two POV characters are similar?
how do you guys smooth over this transition? Do you write big chunks in one MC's head and then go back to add the chapters told from the other MC's perspective? Or do you switch back and forth (and if so, how do you do make this easy?)?
The basic way to write two distinct POVs -- IMO -- is to write good POV.
There's a good many books of advice on how to do POV. Stuff on the net as well.
Look
here, where she's talking about an exercise on stream-of-consciousness.
Here and

And we got an exercise on visualization
here, which is a writing technique helpful on getting into POV. Talking about visualization, see

Related to that -- another POV exercise
here,

here talks about POV and focus.
Hope some of this is useful to you.
