Please refer below snapshot, where 'Set up SSO' objective start date has been changed to 15th JAN 2019, but start date of underlying task did not changed. (e.g. Send customer SAML Metadat)
I have tried this in different org and it looks product bug.
Most of the clients using Success Plan complaining on same thing, as it is not feasible to change start date of each and every task.

Thanks for sharing this. Let me know if i undestand this correctly : you need the tasks start date to always be more that (or equal to) the Objectives start date. So do users generally change the start date of the task or the objective ?
If the user is trying to change the start date to something less than that of the Objective, is the expectation to not allow the user Or automatically change the start date of the objective (and should this change in start date of an objective impact other tasks?)
If the user is changint the start date of an objective (to something more than the start date of any underlying task) should the start date of only that task be changed or all tasks (since there might be other tasks dependant on this task)?
