Sure. Yes, that's exactly right. I actually never liked having to VIEW stakeholders (and roles) in one place and having to go to a different place to ADD stakeholders, but I had accepted it as just one of those things to live with. But now we cannot add them at all (or at least I don't know how to). Below is the whole screen we see now (there was a warning that we might be missing some capabilities of our form, but I don't know enough about the environment to resolve this issue):

it's as if our additional block on the form that allowed us to add stakeholders got "lost". I don't know how we edit this new form to include that section. I really don't want to have to re-develop the whole application just so we can add stakeholders. perhaps we need a lesson in how to modify forms in the new environment?
Thank you for your prompt attention. I really would rather resolve this than to tell Microsoft "roll us back to the prior interface" because as I understand it, we HAVE to move to the new interface by December 1, 2020. And, I bet there are new capabilities we would like to capitalize on anyway. My problem is that there's *so* much documentation, tutorials, etc., I can't find the stuff I care about. We just want to be able to manage opportunities, contacts, and maybe leads.
