@Kevin Mitchell Leonor this is tough for not only CS but also Sales and Marketing teams. Have you had the chance to enroll your peers in working through this yet? Sales doesn't want to lose those customers (or worry about clawbacks) and Marketing invests way too much to see these customers go.
Some things within our control as CS Leaders are time to value and proactive communication. What is your definition of adoption and how fast are your customers achieving both that product adoption and business outcomes? Customers are more likely to stay on if you are meeting their needs and addressing their pain points head on.
