They don't seem to report it annoyingly. They use 92.5% churn, 95% gross margin and 10% discount rate in their investor presentation to calculate LTV though and have previously stated (last year though) net retention is 113% as average customer value is increasing more than churn. Not quite churn though, and not recent. They should definitely add to at least investor presentations.

They imply:
LTV=0.95/(1-0.925/1.1)~=6 years worth of revenue not including increase in customer value. LTV:CAC can easily be calculated from this
